- The Flirty Braidy is a single layer midsole with arch support, which sits on a non-slip Rainbow bottom, with a Twist! The classic leather is top grade nubuck leather that is polished, and finished giving it a fresh, clean, and classy look. The top sole is embossed with the Rainbow logo. The narrow strap has an asymmetrical design featuring a braid on the outside straps and top stitched leather trim on the inside straps. The toe piece is our new V style construction and is wrapped with soft leather for comfort.
