Rubber sole The combination of Zoom Air cushioning in the forefoot and soft, responsive foam helps you harness your power to speed down the court. A molded TPU piece on the outer front is designed for one of Giannis' most effective moves. It helps contain and stabilize the foot through the Euro step motion. The outsole rubber is separated into 2 areas with a rigid, supportive piece in between. This helps reduce weight and improves flexibility. The names of Giannis and his 4 brothers (Alex, Francis, Thanasis and Kostas) are molded into the outsole. Rubberized heel clip helps you pull on the shoe. Giannis possesses a freakish combination of height, length and speed rarely seen in the league. The Zoom Freak 2 harnesses his power and helps enable him to generate force to help drive him down the court. A molded overlay caps the outer toe area to help contain Giannis' devastating Euro step move.
