If you are looking to replace the old non-adjustable BYOB's, don't look here! They just are not as comfortable as the old one's. Due to the adjustability, they are more stiff and can rub your feet a little. The soles are the same and just as comfortable though. I loved my old one's and they started to tear after 3 years of strong use, so I was forced to purchase new ones. The deal at dogfunk.com is the best out there, but just don't expect them to be as comfortable.
