The fan favorite made waterproof. Re-engineered for a better fit with more comfort and more sustainable materials. A new increased midsole and updated CloudTec configuration make landings even softer and more stable. The breathable waterproof membrane locks liquid out and, with the speed-lacing system, you can forget about tying knots. Want classic laces? There’s a pair of those in the box too. The fully waterproof membrane keeps the elements out and lets feet breathe.
