How long have you been using your walking shoes? They don’t have to have holes in the soles to be ready for the garbage bin. They don’t wear out evenly and the padding that protects certain parts of the feet loses its punch. I recently found this out the hard way â€“ keeping my MBT’s too long because of their cost. I have a bruised heel that is taking a long time to heal, bad pun not intended. I broke down and got a new pair from www.blissworld.com and I see where they are making them for men now, too!
