The Mountain Master is loaded with features for hiking. For starters, it sports an upper constructed fully of leather with standard double stitching and quadruple stitching in the high stress areas, ensuring that it´ll stand up to the abuse you throw at it. The Mountain Master has a fully padded opening for comfort. It has injected polyurethanemidsole for cushioning impact. It also has the unique Five Ten S-fit lacing system, which in theory moves the lacing to a more comfortable position.
