We are arguably living through the most pivotal period in the history of running shoes. Never before has picking a race-day shoe had as significant an impact on performance as it does today. A growing body of research confirms this: Studies show that modern super shoes can improve running economy by up to 4 percent, or more, translating to significant time savings in races.

Fastest Shoes From the 2025 Western States 100

The 2025 Western States 100 was everything we expected: fierce competition, scorching heat, and a spotlight on cutting-edge trail running shoes.

Plus = Plush: Nike Vomero Plus First Run Review

Nike is in the middle of a major overhaul of its training shoe lineup. For several years, the brand has been pouring much of its innovation into carbon fiber racing shoes like the Alphafly 3 and Vaporfly 4, and competitors like Hoka, Asics, New Balance, and Brooks have surged ahead in the daily trainer category. Recognizing the growing demand for max-cushioned trainers, Nike has overhauled its everyday cushioned-shoe lineup and is creating three distinct versions of the classic, trusted Vomero....

Do Plates Really Matter In Trail Running Shoes?

If you’ve been following the evolution of road running shoes over the past eight years, you’ve heard of super shoes. These highly cushioned racing shoes combine advanced foam with a carbon-fiber plate embedded in the midsole.

Nimble, Durable, Comfortable Trail Tackler: Mount to Coast T1 First Run Review

Boutique running shoe brands are having a moment. Thanks to advancements in materials (particularly foams) and a flurry of innovative shoe design, smaller companies are now producing footwear that rivals—and in some cases, surpasses—the offerings of traditional big brands. One emerging brand quickly gaining recognition as a serious contender is Mount to Coast. Founded in April 2024, the Hong Kong-based company’s mission is to design a shoe capable of withstanding the rigors of ultra-distance run...

The Lightest Super Shoe Ever Made: Asics Metaspeed Ray Review

While runners work to optimize lungs, legs, and heart (physical and metaphysical) to leave it all on the race course, shoe companies are locked in their own race, battling each other to build the ultimate race-day super shoe. Looking back, there have been two major turning points in the evolution of racing shoes. The first came in 2017 when Nike unleashed the Vaporfly 4%, the shoe that changed everything by enhancing running economy. The second was in 2023 when Adidas introduced the Adizero Adio...

I’m a Running Coach—Here’s How I Trained for the Boston Marathon in Just 8 Weeks

On February 20, just eight weeks out from the Boston Marathon, I got the chance to run this year’s race—and said yes. I had been running regularly, but I was nowhere near marathon shape. My longest run in the previous two months was six miles. I hadn’t gone beyond 12 miles in years. And my last marathon? That was 12 years ago in New York. As a coach for recreational and competitive age-group runners since 2014, I often get asked by prospective clients if they can get ready for a marathon in just...

The Nike Vaporfly 4 Is a Drastic Departure from the Vaporfly 3. Is That a Good Thing?

It’s no exaggeration to say that the Nike Vaporfly 4% was one of the most groundbreaking running shoes ever created. When it debuted commercially in 2017, it stood apart from every other racing shoe on the market, making claims that it could increase running economy by 4% (which, lab results showed, turned out to be true). From its futuristic thick-soled design to the loud, almost obnoxious slapping sound it made with each stride, the Vaporfly 4% sent shockwaves through the running shoe industry...

Nike Vomero 18 First Run Review: Bigger, Plusher, Smoother

Whether you like it or not, today’s running shoes are getting thicker and more cushioned. Thanks to lighter, bouncier, and more resilient foams, brands can now stack more foam underfoot without sacrificing performance. The previous stack ceiling used to look more like 30-40 mm, but as the new 46 mm Nike Vomero 18 proves, 30-40 mm is more like a jumping-off point, but why? Historically speaking, adding more foam meant creating a less stable platform, but modern engineering has tackled that issue...

More Super, Less Stable: Adidas Adizero Adios Pro 4 First-Run Review

Changes are not taken lightly whenever a brand updates a running shoe, especially with a flagship shoe like the Adidas Adizero Adios Pro, and Adidas took its time. While most shoes see updates every 12 to 18 months, it’s been over two years since Adidas updated its most popular racing shoe. In an industry where running shoe technology is constantly advancing, two years feels like a long time between updates. Adidas made substantial strides in the super shoe space during that period, most notably...

The Best Massage Guns, According to an Expert Running Coach

As runners, our muscles take a beating. With each stride, our legs will absorb an impact equivalent to 1.5-2.5 times our body weight. The constant pounding, mile after mile, can lead to wear and tear on our muscles and joints. Recovery tools like massage guns and foam rollers offer a targeted way to reduce pain, enhance blood flow, and keep muscles feeling fresh for the next run.A 2023 systematic review of studies published in The International Journal of Sports Physical Therapy found that repea...

The Best Affordable Running Shoes Under $100, According to Our Testing

Running is not the simple and inexpensive sport it once was. Previously, all you needed was a pair of decently priced running shoes and some clothing, and off you go. Today, running has become a more expensive, gear-centric pursuit—high-tech running shoes, GPS watches, and expensive moisture-wicking apparel are all part of a runner's daily wardrobe, not to mention all the post-run recovery gear. Luckily, plenty of well-made, affordable options are still available, especially when it comes to run...
