Our kids are made with top grade nubuck leather for durability and comfort, they are a single layer but do not have an arch because little feet don't quite need them yet. We use a nonslip bottom sole, which is embossed with the Rainbow name. Flirty Braidy has a narrow strap with an asymmetrical design, featuring a braid on the outer strap, and a top stitched leather trim on the inner strap. Itis all double stitched with bonded nylon thread for durability. We use the bestso that there is no fraying, and the stitching will not pull out. The toe piece is wrapped with soft leather for comfort between the toes. They are finishedoff with our Original Rainbow woven label on the right toe.
