The Noise boot utilizes a flex zone to complement a rider?s style. Whether a rider is more rigid and upright or knees-bent and crouched, the overlay forms without a pressure point. The Option 2 wraps around the top of the rider?s foot with an elastic independent TPU overlay for a locked-in feeling. A formed EVA heel and toe complete this supportive package boot.
