Rubberized heel clip helps you put on the shoe. The combination of Zoom Air cushioning in the forefoot and soft, responsive foam helps you harness your power to speed up the terrain. The rubber outsole is separated into 2 zones with a rigid support piece in between. This helps reduce weight and improves flexibility. The names of Giannis and his 4 brothers (Alex, Francis, Thanasis and Kostas) are moulded into the outsole. A moulded TPU piece on the outer front is designed for one of Giannis's most effective movements. It helps to hold and stabilize the foot thanks to the European walking movement.
