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 in this sleek and stylish slip-on.
