Mixing the perfect balance of speed and stability, the GEL-DS Trainer® 21 continues to incorporate all the treasured features with a touch of newness. Lightweight Dynamic DuoMax® Support System and Propulsion Trusstic provide a stable ride while the new Seamless Upper creates a better and more comfortable fit. Linking all the componentry together is the Impact Guidance System® which improves the foot’s natural gait from heel strike to toe-off.
- Impact Guidance System (I.G.S): ASICS design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off.
- Rear foot and Forefoot GEL Cushioning Systems: Attenuates shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle.
- Dynamic duomax Support System: This evolution of duomax system enhances stability and support, with reduced weight and increased platform support.
- Solyte Midsole Material: A lighter weight midsole compound than ASICS' standard EVA and speva. Also features enhanced cushioning and durability.
- Propulsion Truss tic: Mimics connective tissue in the foot by creating tension as foot enters propulsion stage.
