What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Comfort that outperforms most lifestyle sneakers, with the FuelCell midsole delivering a noticeably lighter, more responsive feel than prior versions while remaining stable underfoot
- Premium materials throughout — suede overlays, quality mesh, and reflective accents — consistent with the line's longstanding build standards
- Versatile enough to function as both a running shoe and an all-day lifestyle sneaker, suiting a wide range of wearers
Reviewers push back
- Sizing is inconsistent across reviewers — some find true-to-size correct, others advise going down half a size, and at least one warns the shoe runs a half size large for those accustomed to other brands
- The redesigned silhouette divided opinion on release; some initially felt it looked generic or Skechers-adjacent before warming to it over time
- Cushioning, while improved, is firm rather than plush — wearers expecting a soft, sink-in feel may be underwhelmed
Reviewers broadly agree the 990v6 is an exceptionally comfortable, well-built everyday sneaker that advances the line's legacy without abandoning its character.
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…”
Where reviewers split on 990v6: Sizing advice splits the reviewers: one channel says go half a size down from your normal 990 size, another says true-to-size is correct, and a third warns the shoe runs a half size large for Nike wearers — no consensus emerges 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
