They tell you (if you read the booklet) that this could cause irritation. I tried these and they initially hurt my feet but I swapped the insoles for redwing moldable inserts and they are some of my most comfortable shoes. The Orthaheel website tells you that it will take a little time to get used to the support in these, which turned out to be true for him. Not the best execution for a potentially great product. I am amazed by the crazy complicated, bike hangers on the market but this is a simple functional alternative. There isnt really space in our bathroom to hang two standard towel bars side by side without putting one behind the door, and neither of us are tall so hanging one over the other without a lot of overlap would have been problematic. Enter the Shotgun seat. My partner says that the fit around the leg is too tight. This waist trimmer is the real deal. The lining and insole are not as soft as that of my UGG boots.
