Put on your new running socks and give them a try.
If you like the idea of barefoot running, but want a little bit of protection from rocks and sharp stuff without sacrificing foot mobility, you may enjoy this inexpensive alternative to minimalist running toe shoes.
All you'll need to make Plasti-socks is 1) a pair of socks (with toes or regular--your choice), 2) a paint brush, and 3) Plasti Dip. You may want to stuff your socks to stretch them to the approximate size of your foot. Water shoes work well inside of regular socks.
