The Rainbow Premier Leather is Rainbow's most well known Men's flip flop. It features a nubuck leather top sole, embossed with the Rainbow logo. The nubuck leather strap is double stitched, and the nylon toe piece is secured with a box X stitch, all with bonded nylon thread. The single layer midsole and arch support are triple glued for maximum durability to the non slip Rainbow bottom. It is finished off with the original Rainbow woven label on the strap, the mark of a genuine Rainbow sandal. If any sandal says Rainbow, it is the Rainbow Premier Leather!
