My hubby really likes his new boots. We're both big fans of Keen sandals, this is my hubby's first pair of Keen boots. He says they are very comfortable, the only thing he doesn't like is that there is a spot on the back on the inside that is made from a different material and it pulls on the sock causing the sock to rub. Other than that he likes them. He is on his feet almost all day, on concrete, for work.
