The 003 is a durable, supportive shoe designed to transition easily from hiking to climbing to running. This laceless approach shoe uses a custom Vibram® sole to accommodate busy days with uncompromising traction. A Bio-Dyneema® upper with elastic providing a fit that remains effective against the test of time. The shoes can easily be attached to a bag via a tab. This edition of the 003 designed with HAVEN features a G+® graphene membrane integrated into the upper lining, offering additional comfort in cold weather thanks to its weather resistance and thermoregulation properties. Effective in all conditions and durations of effort. We recommend adding 1/2 size larger than your normal size.
