Introducing the Sallie Slip On un-sneaker by YES. Her bold and functional sole weds architectural use of arches and light weight space age material. Cutouts in the sole create arches which enhance shock absorption and ease of movement.The ultrasoft and luxurious NCS Natural Comfort System linings conform and shape to the foot. Dense leather fibers provide additional cushioning and its naked quality allows the foot to breathe and wick away moisture. The sealed, air-wrapped sock traps a cushion of air between layers of foam creating a pillow-like feel with every step you take. Pickleball friendly.
