Make no mistake, this is one shoe that doesn't scrimp on the technology front. The advanced upper combines microfibre leather, heathered textile, thin tpu film and climastorm protection to deliver an ultralight, performance shoe. They may even last as long as your sneakers do! these are also unit washable! They feature a steel-toe structure, with extra cushioning in the toe and heel area, which protects against the hardness of the shoes.
