I have flat feet so I bought the wide version of these boots to accomodate my orthotics. I pulled out the factory insoles and was pretty impressed with the quality. Most of the insoles I've pulled out of boots have been flimsy and thin. Not these. They were pretty beefy and padded. Any company who would spend the money to put a quality insole like this takes pride in their product. Anyways, I replaced them with my custom orthotics which went in easy. I've had them now for the past three weeks and they are excellent. I work on the flight line and have these on for 12+ hrs a day and they still feel great at the end of the day. I highly recommend these boots!
