"Will you be worried about looking silly while wearing them?"
I wear them all the time.. recently at gyms but used to wear it in the park when it was warmer..
In both places, I was stopped, asked in a very polite manner either "what are those?" or "I've seen those, what's your opinion of them?". People were curious, and while they thought it looked weird, they never once seemed to look down on me for my funky style. Plus it helps to get the most basic black color.
I like the idea, but I don't think I could handle looking that silly. I've been running in Nike Frees, which are nice, but not all that different from any other Nike. Can anyone recommend a barefoot simulating shoe that looks more normal?
