Saucony Endorphin Speed 5 Review (2025)

Saucon Endorphin Speed 5 Review
By Matthew Klein

The Saucony Endorphin Speed 5 has been an incredibly popular shoe since its debut. It was originally designed as a more flexible, nylon plated alternative to the carbon plated Endorphin Pro. This stemmed from research Saucony participated in, suggesting that different people respond best to different levels of stiffness. Rather than just being an alternative racing shoe, the Endorphin Speed became incredibly popular as a lightweight trainer. The lighter weight, mild stiffness and PWRRUN PB that provides a high amount of cushioning has carried this shoe for years. Like many shoes, its personality has changed over its lifetime. Version 4 was more aggressive, with a firmer feel than was faster but bottomed out over longer distances. Version 5 corrects that, improving the transition and cushioning while staying true to the Speed line. 

Best Running Shoes for Walking (2025)

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.

Between Two Feet: Nike Vaporfly 4 and the Impact of Geometry Changes to a Shoe
Doctors of Running Podcast, Episode 243

If you've been following us for a while, you know that Matt & Andrea often experience shoes completely differently, so on this episode they get together to compare & contrast their experiences in Nike's major overhaul to the OG of supershoes: the Vaporfly 4. With a shorter stack height and narrowed down platform, this nimble racer offers a vastly different ride from its big sibling, the Alphafly 3. Andrea loved Vaporfly 3, so how will she feel about the updates? Matt's often found the Vaporflys too unstable, so will that continue? Tune in to see if you side more with Andrea or Matt!

Mizuno Wave Horizon 8 Review (2025)

Mizuno Wave Horizon 8 Review
By Matthew Klein and Bach Pham

Mizuno's Wave Horizon series has always featured a really unique stability set-up that somewhat predicted the future of stability when it released. Moving away from medial posts, it used the kitchen sink of other stability mechanisms from dual (triple!?) density midsoles to unique geometry and width to create a highly stable ride that suited a large variety of runners. The one issue, however, with past models is that it wasn't exactly the most versatile piece, often being weighty and not very fun to take on the road. The Wave Horizon 8 is a major revamp, however, that amps up cushion and delivers a surprisingly fun ride that can do just a little bit more than its predecessors.

Brooks Ghost Max 3 Review (2025)

Brooks Ghost Max 3 Review
By Matthew Klein

When you test as many shoes as we do, you quickly learn that there are some shoes that you will absolutely love and some that you will not be able to get along with. The original Ghost Max was a risky move for Brooks that paid off. A dramatic departure from the clunky, stale Dyad series, the Ghost Max was supposed to be an orthotic-friendly training shoe that took off given the comfortable transition similar to the old Pureflow series (RIP). Like most second versions ruined because too many people got involved, the Ghost Max 2 was a completely different shoe. A short fit, an absolutely clunky heel, a massive weight gain all but ruined the shoe outside of a more stable neutral and even more orthotic-friendly ride. Version 3 finally corrects most of these issues and brings about a more balanced shoe. A return of a smooth transition, a truly stable neutral, orthotic-friendly ride, and a far better fitting upper brings this series back on track.  

New Balance FuelCell Rebel v5 Review (2025)

New Balance FuelCell Rebel v5 Review
By Matt Klein, Andrea Myers, and Nathan Brown

In the age of maximal stack heights, plates/super stiff rides, the Rebel series continues to be defiant with its flexible, non-plated sole. An incredibly popular series since its inception, the Rebel has maintained its place as lighter, faster shoe that has functioned as a lightweight trainer for some and a racing shoe for others. Version 4 brought some significant changes to the series, including a wider shape and fit that contrasted greatly with the prior version. The positive was an improved PEBA based FuelCell that gave the series an increased performance edge. Version 5 has been shrouded in a surprising amount of secrecy, yet delivers as a true upgrade of the prior version. A large stack height increase, a new FuelCell blend and small improvements in outsole durability continue to move this series forward while maintain its rebellious status.

ASICS Metaspeed Edge Tokyo Review
By David Salas

ASICS athletes and footwear has been performing very well recently at Abbott World Marathon Majors. Many people thought their athletes were competing in the previous version of the ASICS Metaspeed Sky and Edge Paris series, but they actually were in the new Tokyo series. The new series most recently brought home the win at the Boston Marathon. The majority of the credit and accolades should go to the athletes for their amazing performances, but you can't help but notice the shoes. Below is our review of one of the three newest super shoes from ASICS.

Brooks Glycerin GTS 22 Review (2025)

Brooks Glycerin GTS 22 Review
By Matthew Klein and Bach Pham

11 years ago, Brooks debuted the Transcend line. It was their first use of the guide rail stability system that would later "transcend" into all their other stable shoes. A now lower stack height of  29 mm / 21 mm stack height was highly cushioned at the time, making for a premium, stable/guided and oddly responsive stability shoe despite the 11.8 oz weight (men's size 9). In 2021, the Transcend became the Glycerin GTS, a Glycerin with guide rails, as Brooks simplified their line. In 2025, the Glycerin GTS 22 pays homage to the original Transcend with a switch to a "DNA Tuned" midsole, providing a surprisingly bouncy ride that offsets the higher weight (relative to today) with strong medial support. A distinctly different shoe from version 21, thanks to the bouncier but firmer midsole and stronger medial support, the Glycerin GTS 22 re-aligns as a rare high-level premium stability/motion control shoe.

adidas adizero Adios Pro Evo 2 Review (2025)

adidas adizero Adios Pro Evo 2 Review
By Matthew Klein

The original Adidas Adizero Adios Pro Evo shocked the footwear world. It was the first true maximal super racing shoe under 5 oz (men's size 9) and the first in this category to hit $500 per pair. While the Nike Alphafly series was hitting $275 and the Adidas Prime X series sat at $300, a massive jump to $500 was insane. While Adidas has an extensive resume of wins and records set by elite athletes in this shoe, the low availability, problem with resellers and durability made the cost one of the many issues that consumers ran into with the shoe. It was truly an elite tool meant for the elites. However, despite its incredibly light weight, the midsole wasn't as responsive as expected. The Pro Evo 1 relied on primarily on that incredibly light feel rather than the incredible bounce that we now expect from super shoes. Fortunately, that has changed with version two. A new midsole design featuring a much greater rocker and lower drop makes for a faster, bouncier and quicker rolling ride. A redesigned fit provides a true to size fit this time with a still barely there upper. While the jury might be out on whether this shoe is worth $500, Adidas has succeeded in moving the lightest super maximal racing shoe forward. 

Brooks Hyperion Max 3 Review (2025)

Brooks Hyperion Max 3 Review
By Andrea Myers and Matthew Klein

The Brooks Hyperion Max line continues its evolution from the original, which was a favorite do it all shoe of Andrea's, but definitely not a "Max" shoe is any sense, to v2, which saw the shoe live up to its Max name by adding 4mm of stack height and a Speed Vault plate. Version 3 has gained even more stack height, retains the Speed Vault plate, and features a midsole upgrade to PEBA-based DNA gold foam. Now a true max cushioned super trainer, the Hyperion Max 3 is a completely different shoe from its predecessors.
