Meet Lyssa, one of the latest styles from our Fusion4 collection. ara has become known for our Fusion4 technology. This Spring/Summer 2020 season we have introduced Fusion4 2.0 featuring a modified outsole with our appropriately named "window to the sole". Lyssa features a wovenstretch upper with stones for a cross between elegant and sporty. Style: 24005 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. Removable Footbed Easily removed insole allows for insertion of custom orthotic device.
