Puma Fast-R Nitro Elite 3 Review (2025): Forefoot Runner's Dream Racing Shoe?

Puma Fast-R Nitro Elite 3 Review
By Andrea Myers and Matthew Klein

For a company that took a decent break from running and jumped back in not too long ago, Puma has been aggressively pushing their performance product forward. The craziest among these has been the Fast-R series. Debuting in version one with a split midsole and an exposed plate, this series has seen complete transformations between each version. The challenge with previous versions has been that version one functioned better at shorter distances and version two had a massive weight gain and design that kept it from being a top contender. Puma clearly did their homework this time (literally too with the research involved in this product) and have produced a racing shoe that easily pushes its way into the top tier of of super shoes. As with most elite tools, who will benefit most from this shoe is worth discussing. 

ASICS Gel-Kayano 32 Review (2025): 8mm Drop!

ASICS Gel-Kayano 32 Review
By Matthew Klein

The Kayano series is one that everyone knows. Whether you have seen them or they have seen you, this has been an incredibly popular premium stability shoe for years. For walking or running, this has been the staple of anyone with stability needs wanting a more luxury ride than the GT-2000 or GT-1000 series. While somewhat consistent for years, version 30 was the biggest change for the series maybe ever. The medial post was removed, the narrow platform widened, the snug fit opened and what emerged from the ashes was a maximal, wider fitting, guidance shoe with a stability system that adapted to the runner. Version 31 was similar with a mild upper update yet what continued to pervade despite the update was a clunky heel transition. Despite the demonstration of great bevels in their faster shoes, ASICS still seemed hesitant to take the full leap to improve their heel transition. That has changed with Version 32. While appearing similar at first glance, the Kayano 32 makes several subtle tweaks that add up to a significant change. Being the first Kayano with an 8mm drop and a smooth transition, maybe these are not so subtle...

Brooks Glycerin 22 Review (2025)

Brooks Glycerin 22 Review
By David Salas 

The Brooks Glycerin is fan favorite neutral daily training shoe. The Glycerin series has complemented the Ghost model as the premium companion for many years now. The big update for the Glycerin 22 includes a move to DNA Tuned for the midsole. DNA Tuned is a nitrogen infused midsole, with tweaks in the Glycerin 22 specifically to be softer in the heel and more responsive through the forefoot.

ASICS Metaspeed Sky Tokyo Review (2025)

ASICS Metaspeed Sky Review
By David Salas

The new Metaspeed series is here! The ASICS Metaspeed Sky and Edge have been the respective super shoes for ASICS over the last few years. These shoes are aimed going fast and having enough cushion to tackle the marathon. The two shoes have slightly different designs with the Sky focusing on the "Stride" runners and the Edge focusing on the "Cadence" runners. The big update to the Sky this year is the inclusion of a new ATPU based midsole named FF Leap. This helps make the shoe even lighter and bouncy than the previous versions. 

Brooks Ghost 17 Review (2025)

Brooks Ghost 17 Review
By Bach Pham and Matthew Klein

The Brooks Ghost is what we call a run retail store special. This neutral daily trainer is classically the model that is often recommended to new runners due to its middle-of-the-road nature. It's never featured the best of the best midsole or crazy geometries or dynamic cutouts that some of the higher tier performance trainers in the Brooks line-up may have, making it a very consistent option for runners. That means those who like the Ghost can keep coming back to the latest model, even years later, and find a similar performance. The Ghost 17, however, breaks the mold a touch by offering one of the best midsoles yet in the series. Is the Ghost finally out to play?

Between Two Feet: Brooks Hyperion Max 3 and Do Super Trainers Make Good Racing Shoes?
Doctors of Running Podcast, Episode 245

Matt & Andrea are back with another installation of Between Two Feet, where they contrast their different experiences in a shoe. Last time it was the Nike Vaporfly 4, and this time it's the Brooks Hyperion Max 3. Brooks completely overhauled the Hyperion Max, one of Andrea's favorite shoes of the past few years, and turned it into a true max-stack supertrainer. With a Pebax plate & a dual-density DNA Flash/DNA Gold midsole, this one's meant for the long miles. Matt & Andrea discuss how their different mechanics affect how they experienced the foam, weight, and geometry of the shoe. They wrap up by offering some supertrainer options as alternatives to super racing shoes.

Saucony Triumph 23 Review (2025)

Saucony Triumph 23 Review
By Matthew Klein

The Saucony Triumph series has had some significant personality changes over the last several years. While continuing to be the premium cushioned model in the Saucony line-up, it has continually switched between a lighter weight, faster feeling shoe and heavier, highly cushioned shoe. With the addition of PWRRUN PB in version 22, the series returned to being a heavier, highly cushioned shoe meant for higher mileage and easy paces. The PWRRUN PB was not responsive, instead tuned specifically to provide higher cushioning for slower efforts. True-to-form with the series' personality changes, the latest version moves somewhat in the opposite direction, debuting as one of the lightest Triumphs ever. With that comes a new, soft and responsive PWRRUN PB midsole, a snug upper and surprising mild medial heel stability. To say that version 23 is different from 22 is an understatement. 

Best Shoes for People with Haglund's Deformity (Shoes without Rigid Heel Counters)

 

Running Shoes for People with Haglund's Deformity
Or, the Shoes without Rigid Heel Counters List

Heel counters are one of the many footwear components that are commented on here at Doctors of Running. Heel counters are (usually) a rigid piece of material embedded in or molded around the upper of the rearfoot. The purpose is to provide structure to this part of the shoe and potentially stabilize the heel. There are now several variations, going from ones that wrap completely around the heel, to split heel counters (a piece left out at the rearmost portion) and even super thin heel counters just to keep the upper from collapsing. While many people do well with these stiffening agents, some with sensitivities at or around their heel sometimes do not.

Nike Streakfly 2 Review (2025)

Nike Streakfly 2 Review
By Andrea Myers and Matthew Klein

With the explosion of super racing shoes in the last 6-8 years, there has been a complete disappearance of super light racing shoes. While many shoes used to flirt with the sub 5 oz and even 4 oz range, the new category of super racers have mostly stayed in the 7 oz to mid 6 oz at the lightest. Even as the next generation of super marathon shoes starts to dip below the 6 oz range, they are still heavier than where older racing flats left off. That all changes with the Nike Streakfly 2. Featuring a 4.5 oz weight with a full length carbon fiber plate, the Streakfly 2 is the answer for those looking for a superlight super shoe meant for fast races from the mile to 5k (and 10k for more durable runners). 

Best Shoes for People with Hallux Rigidus (Shoes With Stiff Forefoot Rockers)

 

Best Shoes for People with Hallux Rigidus
Or, the shoes with stiff forefoot rockers.

One of the more commonly affected joints in the foot is the first toe. Also called the "Hallux", the major joint where the toe bends can be impacted by a variety of pathologies. Bunions (Hallux Valgus), gout, turf toe, and sesamoiditis are a few of the conditions that may impact this area. One of the more common problems is a stiffening of this joint, called Hallux Rigidus. This is a fancy term for loss of motion at this joint, which may be caused by a variety of things.
