|My next pair will have individual toe holes.|
Instead of jumping on eBay as Barefoot Josh suggested to buy cheap toe socks, I dove into my sock drawer for a pair of ordinary tube socks. Next I used my red-handled serrated scissors to cut two holes in each sock, one smaller hole for my big toe and one large hole for the rest of the little toes.
I knew I would need to have some way to keep the socks from riding up when I squeezed into the Vibrams, which explains the separate holes. However, there was still some toe wedgie action, which may need to be addressed in future models of my toe-less socks.
Unfortunately, I picked a day when the temperatures were in the high 50s to road test my new invention. The good news I guess is that my feet were hot, but the socks did not impede my comfort or stride in any way. Bring on the cold!
