I work in retail and am on my feet 6-8 hours a day. These shoes have a lifespan of six months in this environment. The rubber on the front of the shoe looks very rough and has some minor scuffs. The inside of the shoe, where the heel and ankle make contact with the shoe, wears so much that the inner fabric wears down to plastic. This gives you a hard piece of plastic that will bang against your ankle with every step you take. Needless to say, the shoes are no longer comfortable to walk on.
