Features Birko-flor uppers Suede footbed lining EVA outsoles for shock absorption Cork footbed for orthotic support Fitting Notes: The Milano sandal is perfect for those who want a little more stability. Featuring two adjustable straps across the top of the foot as well as an additional adjustable heel strap, these sandals are suitable for narrower and broader feet. The Birko-Flor straps do not stretch as much as leather and are softer to wear in so they're a good choice for narrow and/or sensitive feet.
