Salomon Aero Glide 4 Review (2026)

Salomon Aero Glide 4 Review
By David Salas

 

Although they are mostly known for their trail models, Salomon has been putting quite a bit of energy into their road models the last couple of years. We saw some big improvements in the foams, weights, and general versatility of their road models. The Salomon Aero Glide 3 was one of those shoes that made such improvements. The Aero Glide 4 expands upon the 3 with a new upper and OptiFOAM2 midsole. The goal is to be a maximum cushioned daily training shoe that is also lightweight.

ASICS Superblast 3 Review (2026)

ASICS Superblast 3 Review
By Andrea Myers and Matthew Klein

 

The ASICS Superblast series is one of the most well-known super trainers. The original version became "the" shoe to get and was the Vaporfly of super trainers. It's tall, surprisingly light and responsive midsole made it a great shoe that did everything from training/long runs to workouts and races for many people. This series has been a frequent suggestion as an alternative to super racing shoes for many runners, particularly those who find them too aggressive or injurious. It was our shoe of the year when it debuted in 2022 and although wasn't perfect, was a clear leader in this category. Version two was odd but stereotypical. Weight was added, the upper narrowed, the ride stiffened and it was still a Superblast but lacked the magic of the original. Version 3 seeks to correct this ship, being one of the first trainers to include FF Leap ad correcting the weird upper fit that plagued prior versions. How this is executed is worth discussing.

Skechers Aero Razor Review (2026)

Skechers Aero Razor Review
By Matthew Klein

 

The Skechers Razor series was incredibly popular back in its heyday. Debuted 10 years ago as a simple lightweight trainer that was one of the first to move away from the podular Skechers outsole. It had the versatility to handle training and faster efforts. The Razor 2 was the shoe I used for my first marathon, pacing the women's elite OTQ field at the California International Marathon. The Razor 3 was an incredible favorite, being the first to feature Hyperburst, one of the earlier supercritical midsole foams. Back when midsole foams were just starting to take off, the Razor 3 continued on the legacy of versatility. There were then many variations, including the Razor+, Razor Elite, Razor Excess, until the series finally returned to numbering. Version 4 solidified the inclusion of a plate, while increasing the weight pushed this version toward being more of a trainer. Version 5 was similar, with an odd fit that made it difficult to enjoy. Just when things looked like they might be over, the Skecher Aero Razor hit the streets. Featuring all the latest technology, including a full-length ATPU midsole, a forefoot H-plate, a racing flat weight, and a highly rockered sole. The Aero Razor tips the scale back toward fast, establishing a new and exciting direction for the series.

adidas adizero Boston 13: Quick Evaluation (2026)

adidas adizero Boston 13: Quick Review
By Matthew Klein

 

The adidas adizero Boston series has been a popular, long-standing performance trainer that has blended the durability for training miles with the speed for workouts and racing for many. It's lighter weight ride shifted dramatically in versions 10-11, becoming a more maximal shoe that lost the nimbleness that prior versions were known for. Version 12 brought the series back with a combination of carbon rods, a top layer of Lightstrike Pro and a lighter ride. While still heavier than the racing-like rides of versions 6-9, it not only signaled but also showed that the Boston was back to being fast. Version 13 is a subtle update that looks different but maintains much of what made version 12 great while still making some improvements.

Best Running Shoes for Walking (2026)

Beginner's Guide to Walking,
and the Best Running Shoes for Walking

By DOR Editorial Team

While this website is called "Doctors of Running," we spend a great time personally either walking in the shoes we test or clinically treating/working with people who are having issues walking. Running usually takes only an hour or two of our day. The rest of the time is spent standing, sitting and walking. Running shoes have become extremely popular for everyday use outside of running due to their comfort. With that in mind, we decided to pull together a guide for those coming here looking for great running shoes specifically for walking or standing. The following guide provides a general overview of walking along with some guidelines you should keep in mind. At the very end you can find a list of recommendations for specific shoes we have found excellent for walking and through personal experience using all-day through our clinical work. 

Salomon Ultra Glide 4 Review (2026)

Salomon Ultra Glide 4 Review
By David Salas

 

Salomon is very well known for their outdoor efforts across multiple sports. In trail running, their name swings heavy. The Ultra Glide 4 is a trail running shoe that is aimed at providing plenty of cushioning for long outings. After reworking the previous model, they have gotten the weight just under 10 ounces, while still maintaining a stable and highly cushioned and rockered platform. The Salomon Ultra Glide 4 offers a lot of versatility while still being plush and comfortable. This is a trail shoe that will agree with a lot of people.

Hoka Gaviota 6 Review (2026)

Hoka Gaviota 6 Review
By Bach Pham and Matthew Klein

 

The Gaviota has been Hoka's long-standing premium stability shoe. It has been quietly working in the background as one of the lighter yet maximal, higher-stability shoes in the market. This fairly popular model has gone without an update for quite awhile. Our review of version 5 is now three years old (2023). It was unique among Hoka shoes as one of the first to feature the H-frame and unlike other shoes in line, it fit wide. Along with popular models like the Kayano and Glycerin GTS, it is commonly seen on the feet of walkers and people in a variety of industries who stand on their feet for long periods (healthcare workers for sure). Version 6 is a long-awaited update that takes everything about this series and makes it better.

Hoka Cielo X1 3.0 Review (2026)

Hoka Cielo X1 3.0 Review
By Matthew Klein

 

The Hoka Cielo X1 series has always been a bit crazy. Version 1.0 was one of the heavier super racers on the market, yet had also one of the bounciest. It was a favorite of many of our team members given the lateral bias that made it an excellent medially stable racer that is still rare to see. Version two went a different direction, dropping a large amount of weight, getting taller and far slimmer. It went the opposite direction, with medial bias that took away its "stable racer" categorization, but trading that for a far more aggressive ride and fit. Version three melds the best of both. The snug fit remains, while a more balanced but incredibly bouncy and fast ride sits underfoot. A central cutout exists rather than lateral or medial, helping further with the shoe's aim to become middle grounded. The Hoka Cielo X1 3.0 is a true distance racing shoe, although who it will work best for is worth talking about. 

Puma Deviate Nitro 4 Review (2026)

Puma Deviate Nitro 4 Review
By David Salas & Andrea Myers

 

Since coming back onto the running scene, Puma has made great strides in their performance footwear. The Puma Deviate Nitro 4 continues upon this tradition by updating their highly versatile and responsive training shoe. The Deviate Nitro 4 can be used for a variety of uses, but with the main intent of tackling uptempo training runs and acting as a training companion to a super shoe. If you are staying within the Puma lineup, that would be the Puma Deviate Nitro Elite 4 and/or the Puma Fast-R 3 respectively.

Brooks Glycerin GTS 23 Review (2026)

Brooks Glycerin GTS 23 Review
By Matt Klein and Bach Pham

 

The Brooks Glycerin GTS over the past few years has become the replacement to the Transcend series as part of the company's goal to simplify their line-up. While the Adrenaline GTS serves as the traditional stability daily trainer, the Glycerin GTS is basically a more premium version with a more modern midsole foam embedded. In this case, DNA Tuned replaces the DNA Loft v3 midsole to offer a slightly airy, more responsive midsole experience. The latest edition also offers some midsole changes that go in line with many core changes that Brooks is working on for 2026.

On Cloudrunner 3 Review (2026)

On Cloudrunner 3 Review
By David Salas

 

The On Cloudrunner is a favorite for many. The shoe is categorized as being a mild-to-moderate stability shoe with moderate cushioning. For many, this shoe works as an excellent option for standing and walking, lifestyle, and logging some easy miles. The Cloudrunner 3 continues upon these themes while adding a plush and premium upper. 

Diadora Mythos Blushield Vigore V Review (2026)

Diadora Mythos Blushield Vigore V Review
By Matthew Klein

 

After years of what seemed like a death spiral, the stability category is seeing some signs of life. A few (emphasis on few) new stability shoes have hit the market recently, providing a few more options for those who need true support. The challenge with these new models is that many still provide a firmer and stiffer ride, forgoing some of the newer midsole technology seen in neutral or lighter shoes. The Vigore V is supposed to change that with a top layer of bouncy Blushield N2 meant to make this stability shoe be a bit more snappy and fast. While the top layer is bouncy, what the Vigore V truly brings to the table is being one of the taller heel drops left on the market (one of the few over 10mm), with a solid amount of heel/midfoot stability and a snappy underfoot feel while still being a traditional stability shoe.

Mizuno Wave Inspire 22: Quick Evaluation

 

Mizuno Wave Inspire 22: Quick Evaluation
By Bach Pham

 

My first Wave Inspire was Version 17, which feels like a very long time ago. Then, it featured a very prominent medial support system. Recent versions have transitioned to a new wave plate design that focuses more on guidance than medial support. The Wave Inspire 22 aims to make subtle changes around their wave plate design, specifically in adjusting their foam and transitioning from 12mm to 10mm. In this quick evaluation, I'll share the good and the bad with this latest update from Mizuno. 

Kane Revive AC: Quick Evaluation

KANE Revive AC: Quick Evaluation
By Andrea Myers

 

The KANE Revive AC is KANE's winter version of their popular Revive recovery shoe. The Revive is a popular recovery option due to its highly breathable upper. However, this makes the Revive less than optimal in cold or wet weather. Thankfully, KANE has come out with the Revive AC, which features a waterproof upper, a Neoprene ankle cuff, and a rubber outsole with 2.65mm lugs for traction. 

Nike Structure Plus Review (2026)

Nike Structure Plus Review
By Matthew Klein and David Salas

 

Nike was quick to debut the new tiered levels of the Pegasus and Vomero series, with a standard, plus and premium model for each. The Structure series has had a delay in the releases, with many stability fans curious and apprehensive to see what of two new rare "additions" to the stability category would look like. The Structure Plus is the first to be debuted after the Structure 26, becoming one of the few stability shoes to feature a "super foam" of ZoomX foam. While not fully ZoomX, the Structure Plus is meant as a bouncier, faster companion to the Structure 26 for those who need a moderate to higher level of stability but still want some super, maximal stack height bounce in the ride. How it actually feels? Let's talk about it.

Saucony Endorphin Pro 5 Review (2026)

Saucony Endorphin Pro 5 Review
By Matthew Klein

 

The Saucony Endorphin Pro is one of the original super shoes. It was in a line of the first true super shoe (ie a plate, superfoam and max stack height) after the Vaporfly series, debuting around the same time as the original Adidas Adizero Pro and the Nike Alphafly Next%.  It has seen a great deal of changes over the years, with a rolling ride in its first two versions, a crazy bouncy and fast ride in its third, and the fourth moving into a higher volume, stable racer. Our contacts at Saucony informed us that many people were starting to use the Endorphin Pro 4 as a trainer/workout shoe and racing in the Endorphin Elite. The Endorphin Pro 5 is an evolution of this concept, where it is designed as a faster racer that is still durable enough for tons of workouts and races. Major updates include the geometry, upper, outsole and plate design. Although it was supposed to be a careful update, it has turned into a completely different shoe.

Best Carbon Plated Running Shoes (2026)

 

Best Carbon Plated Running Shoes
By DOR Editorial Team

↓ Jump to Carbon Plated Shoes A-Z |  ↓ Jump to Best Plated Shoes for 5k to Marathon

The current trend in racing shoes has been toward super foams and carbon fiber plates. Although plates have been used in the past, their popularity has surged. A new age of fast shoes has come about and now a variety of companies have released their products (some in small batches). For the first time (almost ever) there is an interest from the general public (and not just the competitive runners) in finding the fastest shoe to get them across the finish line. We at Doctors of Running thought it would be helpful to have a guide to all the current models to help you choose if and which one may be right for you.

Saucony Endorphin Azura Review (2026)

Saucony Endorphin Azura Review
By David Salas and Andrea Myers

 

Saucony has been widely popular for several of their models in the Endorphin lineup. Ranging from daily trainers to racing shoes, the series normally is characterized by having a noticeable rocker in a responsive package. Previously, the lineage of shoes were the Endorphin Shift, Speed, and Pro, respectively. This line was expanded into new models like the Endorphin Elite, Endorphin Edge, and Endorphin Trainer over the years. With the Shift discontinued, the void for a daily training shoe within the Endorphin lineup is being filled with the new Saucony Endorphin Azura. 

Saucony Guide 19 Review (2026)

Saucony Guide 19 Review
By Bach Pham and Matthew Klein

 

The Guide series from Saucony has been a reliable stability series for runners with stability needs. The Guide transitioned from being a shoe for those with higher stability needs thanks to a medial post design to a more universal, guidance-based model in recent years. In this review, we cover the latest version in the series which makes some midsole updates to help refine the modernized Guide they introduced with the 17 and 18.

ASICS GT-4000 4 Review (2025)

ASICS GT-4000 4 Review
By Matthew Klein

 

While the stability category has continued to shrink over the last 5-10 years, the motion control category has almost been eliminated. Shoe series like the ASICS Foundation, Mizuno Paradox/Alchemy, Saucony Redeemer and others have long been discontinued, leaving only a few left for those looking for high stability. The ASICS GT-4000 is one of those that has quietly stayed under the radar for the last few years, but still been a staple for those looking for a maximal stability shoe that has a full-length medial post. The ASICS GT-4000 4 continues to have a place in running footwear for those looking for higher levels of and more traditional stability. 

The Best Stable Neutral Running Shoes (2026)

When we put together our Guide to Stability, we also helped define a segment of running shoes that we felt existed, but wasn't amplified. We ended up coining the term "stable neutral" to help put a name to the trend. Stable neutral shoes have steadily become a growing part of the industry in recent years. Especially as maximal cushioning as gone from a corner of running to the norm, companies have been working to balance these tall stack heights with a variety of design features to create stable platforms. In this feature, we further define stable neutral shoes and offer our current favorites in the market today.
