Brand New in Box Men's Sz 11.5 Color: Black (onyx) This is a high-top silhouette joined with a molded heel counter than locks the foot in place to prevent slipping.

The Load ‘N Launch technology (forefoot compression springs) in the insole is what helps develop not only extra comfort for the foot but is critical to the accelerated vertical leap the APL Boomer has waiting to give you. The boost is pronounced enough that the Load ‘N Launch tech has been banned by the NBA!
