Critics' Concensus
Overview
The Ride
Reviewers generally describe a lively, bouncy, highly cushioned ride that stays responsive at moderate-to-fast paces; some note it can feel a bit blocky or less smooth when jogging easy. Multiple reviewers likened it to a lighter, bouncier version of Asics' Superblast line.
Fit & Feel
Testers report a light, breathable woven/mesh upper with secure lockdown; the forefoot runs on the snug side (some pressure over the pinky toe) and the tongue is thin—watch for lace bite if over-tightened.
✓ Pros
- Impressively low weight for the stack height
- Versatile for a wide range of paces
- Grippy ASICSGRIP outsole
✗ Cons
- Premium price
- Narrow toebox
- Not the most stable choice for those who need guidance
Bottom Line
Best for: runners who want a high-stack, bouncy trainer that can handle long runs and workouts without a plate;
Consider alternatives if: you prefer a roomy forefoot or need added stability; you want a "do it all" trainer at a lower price
