 I would say maybe take a look at the shoes and make sure they're fitting you appropriately and that they offer you the right amount of support to start with. And then I would probably say go see your local podiatrist to see. I'm kind of curious. I mean, here's Tim wearing slippers every day for months. Now, I have really flat feet and I'm just wondering, you know, slippers, generally speaking, don't have any support. Could that have had a contributing effect?
