Some people lament these sandals as the second coming of jesus, it would seem by the reviews.  My previous sandals from another company gave me 7 good years, and I was looking for a follow-up pair for that purpose.  After wearing these for a few weeks, I'm not convinced.  Initially, I only wore these a couple of hours at a time, and did minimal walking to try and break the sandals in.  However, they've failed to completely break in, and one has a large bump/knot on one of the sandals, which has left me with a painful blister after wearing them for a couple of hours. The other sandal doesn't have this defect, so I'm not sure if I should try to request a new one or manually fix it.
