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
- 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 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 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
