Initial fit should allow the foot to settle naturally into the sandal's foot bed so your foot sits inside the edge of the foot bed all the way around. The two front adjustable straps should fit comfortably on the foot once the buckle at the ankle is adjusted to a comfortable position. Broad, Contoured Footbed: Our broad contoured footbed with a soft Super Suede cover is molded so the natural arches and curves of your foot are cradled in the sandal. This allows you to maximize the shock absorbing qualities of multilayers of comfort. SAS Foot-Shape Last: This special last follows the natural shape and contour of your foot, providing all-day comfort. SAS All Day Comfort Sole: The wide sole base provides increased stability and maximum shock absorbency. This feature, along with the contoured footbed and multi-layered insole, works to "rebound" every step and provide you with all-day cushioned comfort.
