It takes about 10 hours or so to break this pair of shoes in. And they are comfortable once this is done. I personally got another probably 20-30 hours worth of wearing these until they completed started to suck. They are made cheap and the insoles have came unglued and folded up in both shoes. Less than impressed considering the money I spent on these. I received these on April 24th, and haven't even worn them since the end of May.
