The AEROCHARGE ENGINEERED STZ TROPHY features the same high performance features and characteristics as the Aerocharge Supreme Knit, but differ in its low-cut silhouette and a visible heel counter with Twin Heel Control for a stabilizing fit, grip and bounch. The shoe has a strecthy, breathable knitted upper with a 360° support for a comfortable fit and protection. Resting atop our unique, lightweight Aerocharge outsole for even more explosive takeoffs. A high performance indoor shoe for the aggressive player with ambitions. Medium/Wide fit: For a narrow fit choose your normal size. For a looser fit go ½ size up.
