The double layer classic leather sandal offers all the great features found in our single layer leather, but with an added layer of midsole and pin line, which starts at the arch and rises towards the heel, for even more comfort and support. The midsole is made to break down 10% under each foot so you have the perfect mold for your individual feet. The top sole is classic finished leather, and is embossed with the Rainbow® logo. The 1" classic leather strap is double stitched, and the nylon toe piece is secured with a box X stitch, all sewn with bonded nylon thread. The layers are all triple glued for maximum durability, and rests on our non-slip Rainbow® bottom. This sandal displays the Original Rainbow® woven label on the right strap, the mark of a genuine Rainbow® Sandal.
