Fusion4 Technology

The 4 in Fusion4 represents the four ways in which the foot individually finds its fit: upwards, to the sides, diagonally and downwards. Superior fit is achieved through a dynamically flexible HiFlex Upper that stretches in all the right places and a Dynergy Sole that varies in the way it yields to pressure and motion in the forefoot and heel. The result is superb comfort without fatigue.
