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…”
Reviewers praise
- Power run plus midsole delivers soft, plush cushioning while retaining enough energy return for daily training
- Durable construction with xt900 rubber outsole and solid build quality that holds up over high mileage
- Comfortable fit with good lockdown and minimal break-in required
Reviewers push back
- Gained weight compared to the previous model, coming in heavier than some competing daily trainers
- Flat knit upper may feel warmer and less breathable than the previous engineered mesh in hot conditions
- Not designed for faster paces or tempo work despite being capable of handling varied runs
“I think this is a shoe that works with you it sort of disappears in a way I think that's really nice”
Where reviewers split on Gel-Kayano 30: One reviewer experienced mild knee discomfort in the first twenty miles due to rearfoot stiffness, which then disappeared; others had no such issue On Triumph 21: One reviewer found the previous version felt dead and unenjoyable but loved this iteration despite identical midsole foam, attributing the difference to training cycle timing
