Designed with a fashion casual athletic upper and performance-driven features, HyperGEL-SAI transitions from workout to hangout for easy all-day wear. A new generation of ASICS signature GEL, the HyperGEL midsole offers premium cushioning, a responsive ride and exceptional durability. **FIT NOTICE** The HyperGEL-SAI has a new premium sock-like fit but also runs slightly shorter than standard. We recommend buying a half size larger.
