Tapering, day 1

After yesterday's disastrous run, my tapering for race day is going to have quite a bit of damage control. Remembering something I saw on Runner's World awhile back, I did a search for "toe caps." I just ordered a pack of these: www.injurybegone.com/products/toecaps.html. While running with something around my toes does not sound like the most comfortable thing ever, a bit of inconvenience is better than a repeat of yesterday... here's hoping they work. In theory, my toe problem was not from shoes being too small; after all, my current shoes are a full size larger than my last pair (of the "updated" make and model).

Anyone used these toe caps before?
