You guys are going to find this hilarious. I went to the other Y in town to use their track as it is bigger and nicer than the Y that I usually go to. Now, this track goes around the main gym unlike the other one which is suspended above the basketball court. I decided to go up to 20 minutes running barefoot on this track. So I did my run (felt great BTW), and as soon as I went to a quiet corner by the track to stretch a staff member said "excuse me, miss" and when I responded he said that proper footwear is required, four people had come up to him and complained (he himself hadn't noticed), there is a sign out front with the rules (which I did not see) and he would have to ask me to leave the gym. So I apologized for not seeing the sign and left, figuring I could just as well stretch in the locker room anyway. It appears I will be trying out the Vibram Five Fingers (which I did have in my gym bag but quite honestly wanted to see what reaction I would get by going shoeless) for running next time I go there--they're not sandals or open-toed shoes, and if I were to step on something my foot would be protected, so tha shouldn't be an issue. I found it sort of funny that I got the boot for not wearing shoes!!
