I've made the decision to forgo the damn orthopedic inserts I've been wearing. To be quite frank, when I put my shoes on this morning and stood up, I felt like I was standing on a couple of ball bearings. I suffered through it this morning, but five minutes ago decided it wasn't worth it, and I would try my luck without them.
The biggest problem is that if the shoes I'm using don't work, then I'm somewhat screwed. I don't have the disposable income to be buying crazy-expensive walking shoes right now, so I'm keeping my fingers crossed (no toes - I think that'll worsen things) that I'll be okay. Otherwise I might have to withdraw and regroup.
