The single layer premier leather sandal is made of top grade nubuck leather top sole that is embossed with the Rainbow logo. The strap, also nubuck leather; is double stitched, and the nylon toe piece is secured with a box X stitch, all using bonded nylon thread. The single layer midsole and arch support is triple glued for maximum durability to our non-slip Rainbow bottom. We finish it off with the Original woven label on the right strap, the mark of a genuine Rainbow Sandal.
