Asics Gel-Quantum 90 Shoes. Drafting off the design of the performance driven GEL-QUANTUM 360™ silhouette, the GEL-QUANTUM 90™ sneaker fuses a technical design that's layered with comfortable cushioning. Implementing a mesh upper that wraps the forefoot with excellent support and airflow, this shoe is also complemented with bold GEL® branding on the heel. Created with a balanced blend of support and long-lasting comfort, this shoe features our injection E.V.A technology in the midsole for a more energized response, while the GEL® technology cushioning in the heel helps attenuate shock from impact. Supplying advanced comfort with a technical design, the GEL-QUANTUM 90™ sneaker continues to redefine the limits of cushioning for performance driven offerings. Imported.
