HOKA Rocket X 3 — what reviewers say
Ride profile: high cushion , neutral stability .
-
Ben Parkes' top Hoka pick; a smooth, stable, and accessible carbon racer suited to 3- to 5-hour marathon runners of all strike types, preferred over the more aggressive Cielo for its comfort and nice rocker geometry.
In their words: "very smooth and stable, however you choose to strike" · "really nice rocker geometry as well, not too aggressive"
-
The Rocket X 3 is an accommodating carbon race shoe with a smooth rocker transition, reliable underfoot consistency, and soft but controlled landings that let the runner focus on the race rather than managing the shoe — good for road ultras.
In their words: "fades into the background" · "good protection for a carbon race shoe" · "smooth, fast option"
-
#8. Fun, nimble, forgiving, easily available. Lower drop lets you land easier on mid-/forefoot without hammering the Achilles. Improved HOKA rubber grip. Good deals available.
In their words: "fun, nimble on foot, very forgiving" · "I love the simple design" · "land a bit easier on the mid"
-
A stable-neutral super shoe with a firm-yet-bouncy dual-layer PEBA midsole and winged carbon plate that Matt considers a potential racing shoe of the year for runners who need medial guidance, while Andrea finds it comfortable and well-designed but biomechanically unsuitable for her push-off pattern; durability of the exposed midsole and outsole is a concern after only 20-25 miles.
Ride:Dual-layer PEBA midsole feels both firm and bouncy with a snappy, fun ride. Full-length winged carbon plate with elevations adds rigidity and lateral/medial guidance. Central midsole groove and wider midfoot create a stable neutral feel without a traditional medial post. Works very well for runners who collapse medially (Matt), but the stability features kept Andrea in inversion longer, overloading her posterior tibialis and causing anterior-lateral ankle pain on faster workouts.
Fit:True to size, more snug upper than version 2 but breathable with a stretchy feel; heel is rounded and comfortable; no sidewall irritation reported even though sidewalls are significant on both medial and lateral sides; plenty of width in the toe box.
In their words: "really both firm and bouncy" · "plenty of width in the toe box" · "chewing up this exposed midsole"
Nike Alphafly 3 — what reviewers say
Ride profile: high cushion , balanced feel , high energy return , neutral stability , moderate rocker.
-
EDDBUD has a soft spot for the ZoomX foam in the Alphafly 3, calling it one of his favorite shoes over recent years, though he feels ZoomX overall has not kept pace with newer foams in the market.
In their words: "soft spot for the Zumax" · "one of my favorite shoes over the last few years" · "design is very much exactly what it was back in 2020"
-
Both reviewers consider it an excellent carbon plate racer that remains one of the best marathon options for its cushioning and protection, but agree it has been surpassed by the lighter, more responsive Metaspeed Sky Tokyo. Still a strong choice for runners who prioritize cushy protection over lightweight agility.
Ride:Cushier and more protective feeling than the Metaspeed Sky Tokyo, especially at the heel. Provides a stable and safe landing with a wider base. Air Zoom pods under the forefoot deliver punch off the toes. Feels like it protects legs well over marathon distance. Great for locking into a pace and holding it, with a slightly cruisier ride character.
Fit:True to size but a more restrictive fit than the Metaspeed Sky Tokyo. Booty-style upper can be hard to get on. Midfoot runs lean and snug; runners with wider feet should take note. One reviewer had zero complaints; the other noted the tighter midfoot.
In their words: "cushier feeling at the back of the shoe" · "feels like it's built like a tank"
-
WINNER of Megan's knockout race-day bracket — her ultimate race-day shoe.
Ride:Forefoot Air Zoom pods give it the edge over the Vaporfly 4. Megan's race-day pick regardless of distance (except Vaporfly 2 which she disliked). Comfortable upper. Heavier than the Metaspeed Ray but worth it. Feels great in the late miles of a marathon.
-
The fastest shoe in the world by many accounts; unique Air Zoom + ZoomX combo.
Ride:Combination of ZoomX foam plus very different (larger) Air Zoom units than Pegasus is what makes the Alphafly so unique and fun.
