Rainbow Sandals' premier leather is on a non-slip Rainbow bottom with a single layer without an arch. Now the kiddo’s can be just like everyone else. The leather strap is double stitched with bonded nylon thread using a box X stitching pattern. They use the best so that there is no fraying, and the stitching will not pull out. The toe piece is a 2000lb military spec nylon and is triple glued inside the sole. They are finished off with their signature Original Rainbow woven label on the right toe. For the toddlers, the three smallest sizes come with a back strap, but if you don’t need it just cut it off!
