ASICS Metaspeed Ray — what reviewers say
Ride profile: maximal cushion , neutral stability .

EDDBUD sees the Metaspeed Ray as a very niche, extremely light but unstable option whose modest price premium over the Sky/Edge makes it interesting, though its specialist nature means it sits unsold on shelves.
Ride:Extremely light but very unstable; uses only FF Leap which feels a little different to the Sky/Edge; niche shoe priced only slightly above Sky/Edge models
In their words: "extremely light, but also very unstable" · "quite a few pairs of these sat on shelves"
-
Kofuzi's preferred ASICS racing shoe — a super-lightweight racer built entirely from FF Blast with a teardrop 3/4 forefoot plate; squishy and potentially unstable for heel strikers but very exciting and the lightest in the lineup.
In their words: "very squishy, very lightweight, but also pops back really quickly" · "the one that I prefer out of these two shoes" · "very exciting and a super lightweight racing shoe"
-
A genuinely exciting hyper-light racer — softer, bouncier, more fun than the Pro Evo 2, and a fraction cheaper. Stability is the only reservation for longer races.
Ride:Very soft and squidgy but transitions fast — you sink but get bounced onward quickly. Heel is particularly squishy (no plate there). Nick ran his sub-32 10K PB at Brighton in it, closed the race the best he ever has. Feels best at marathon pace in training (cruise control). Both testers worry about stability at full marathon distance given the softness, but Nick noted every time he goes back to it, it's less wobbly than he remembers.
Fit:True to size with softer, more flexible upper than the Pro Evo 2. More clearance at toes, bit easier to splay. Heel tab sits a bit more comfortably under the Achilles than Pro Evo 2's.
In their words: "soft and very bouncy" · "so fun and bouncy" · "so soft, so squidgy"
-
Megan's pick over the Sky/Edge Tokyo. Knocks out the Adidas Pro 4 in her bracket — soft landing + really propulsive forefoot once you adjust to the instability.
Ride:FF Leap is the lightest, most energy-returning foam (shows wear visually but performs the same over time). Lighter, bouncier, less stable than the Sky/Edge Tokyo. Built for one thing: light, fast, bouncy. Megan put 100 miles in and loved it more each run. Thomas: maybe more than half-marathon distance needs the stability of the Sky/Edge.
Nike Alphafly 3 — what reviewers say
Ride profile: high cushion , balanced feel , high energy return , neutral stability , moderate rocker.
-
EDDBUD highlights the Alphafly 3 as an ideal marathon option — plenty of cushion and a wide base keep it stable despite the very soft heel.
In their words: "a very wide base as well" · "not really unstable at all" · "ideal marathon option"
-
Ben's marathon PB shoe — a top super-shoe pick with PEBA foam and carbon plate, offering exceptional protective cushioning for long race distances.
In their words: "ran my personal best in the marathon"
-
The Alphafly 3 is eliminated in the group stage, described as a former great that is aging gracefully but no longer at the top.
In their words: "a former great, aging gracefully, but still not quite getting through"
-
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.
