The 3mm Split Toe Booties are all about warmth and flexibility. They’re built with a single layer, rubber molded sole that keeps your toes toasty without sacrificing board feel. They also feature a neoprene padded velcro arch strap to keep everything locked in place and a leash barrier to help avoid the dreaded leash-toe tangle. The no stitch, fused heel also makes these booties a breeze to put on and take off.
