What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Stability feels subtle and centered rather than rigid—many reviewers say you would not know you are wearing a stability shoe
- Wider platform and roomy toe box accommodate foot swell and offer more space than previous Kayano versions
- Soft, plush upper with thick padding around heel collar and gusseted tongue provides comfort for long efforts
Reviewers push back
- Upper runs hot and lacks breathability, especially in warm conditions—thin socks are necessary
- Heavy for a daily trainer at over 10 ounces in men's size
- FF Blast Plus Eco foam feels less bouncy and responsive than non-Eco versions found in other ASICS models
“I think this is going to be a shoe that the max stability lovers are going to come back to but I think maybe some Runners who haven't been in a kind of for a while are gonna see…”
