The TYR® Dropzero shoes are lighter than CXT-2, making them ideal for your everyday runs. Their new external thermoplastic polyurethane (TPU)-molded counter enhances stability through lifts and strength exercises. These low-top shoes are made of a polyester upper, an ethylene vinyl acetate (EVA) insole, and a polyester lining. The TPU stability wrap adds durability for rope climbs and handstand pushups. These lace-up shoes feature a TYRTAC rubber outsole that helps keep you grounded through different lifts and movements.
