I used these Mountain Trainer Lite Men's Shoes from Salewa on a 50-mile backpacking trip shortly after I purchased them. Hardly any break-in time was required, and I never had a blister from the shoes.
They provided excellent support the entire time. There is some wear, though, on the sides where the shoe flexes for the toe box than I have experienced with my other Salewa shoes. So far there is no tearing of the material, but there is some fraying that I think will reduce the life of the upper.
