The Microtex upper is supple yet strong and stable for a comfortable and consistent fit. It is assembled in a sleek and streamlined yet highly ergonomic pattern, offering you the protection you need. Overcurve is a shoe construction featuring a staggered collar that wraps around the ankle, tracing the natural misalignment of the ankle’s two bony protrusions: the lateral and medial malleoli. The result is an asymmetrical shape, with the throat of the shoe curving over the foot from its outside to its inner side. The closure is simple and secure, powered by a micro-adjustable Boa® IP1 dial.
