The Innox Pro GTX LO Ws has a fully synthetic, tightly meshed upper which is lightweight and highly breathable for wearing in warmer weather. The double injection mid-sole is made of proprietary DynaPU®, giving much greater cushioning and energy rebound than other shoes. The innovative Monowrap support frame provides the support on more challenging terrain, without adding any weight or bulk. The Innox uses a highly breathable form of Gore-Tex lining, meaning your feet stay comfortable and dry in all conditions. Built on a women's specific last, this shoe is 100% vegan.
