Gel-Quantum 90 2 Street ShoesColor: Grey Drafting off the design of the performance driven GEL QUANTUM 360 silhouette, the GEL QUANTUM 90 2 sneaker fuses a technical design that's layered with even more GEL technology based cushioning than its predecessor. 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, while reflective details accent the tiger stripes on the sides.
