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.
HyperGEL™ Technology: High performance design with HyperGEL™ technology beads integrated into the midsole enhancing rebound and cushioning while reducing impact.
MONO-SOCK® Technology Fit System: An elastic internal sleeve which replaces a traditional tongue providing a ""sock-like"" fit.
Asymmetrical Lacing Design: An anatomically correct lacing environment that reduces potential for irritation and provides improved comfort and fit.
