I bought these shoes about a year and a half ago. I wear them so seldom that the sole is in near perfect condition. When last worn, the glue on the soles had completely evaporated. I contacted Merrell and explained the situation. They refused to do anything about it as it had been more than a year since purchase and denied a manufacturing defect. Got a 30% discount on a new pair of shoes but with this quality I wouldn't want to buy from Merrell again.
