This shoe looks very nice, but it easily cuts into the heel and causes blisters. The heel tip literally scratches you. The sole is too soft, which sounds counterintuitive (wouldn't you like a softer sole?), but it's like walking on a sponge yoga mat instead of real shoes. The actual tread is very soft, which I think provides excellent traction, but wears out quickly. I only wore this shoe for 1 day and feel lucky to be able to return it. Sperry has not done any thorough research into this.
