Women Walking Leather Nubuck. This sandal, with its sporty, feminine allure, sets itself apart with its lightweight design. The detachable insole, equipped with SOFT-AIR Technology, can be replaced with your own insole (especially an orthopedic one). The EASY-WALKING TECHNOLOGY system stimulates muscles which are often neglected during a normal walk and supports the natural functioning of the foot, acting as a shock absorber. The adjustable adhesive straps combine perfect comfort with the perfect fit. The leather lining favours a healthy climate and adds exceptional comfort.
