Nashbar Tennis Shoe adapter

I tried these once. Thought they would be handy to just hop on and ride the mile to school, but I guess I didn't work with them enough. They kept falling off and actually, I didn't even bother to tighten the pedal. I just went ahead and purchased the two-sided pedals. If anyone would like to try them, send me your addy and I'll drop them in the mail for you. They're light, so we won't even bother exchanging postage, I'll just send them, free, to anyone who wants to give it a shot!

Here is the link (I hope)
