And does it feel natural or uncomfortable to you? Both outdoors and indoors?
I'm asking this question because of the common practice - among girls at least - of taking off your shoes to run faster barefoot. I can understand this with high heels, but flip-flops? Just walking on gravel hurts my feet so much that I can honestly say I move about a LOT faster in flip-flops.

I'm starting to think that walking barefoot, like learning languages, is something that you pick up easier when you're a kid ;)

... walking barefoot outdoors, I mean, since I'm always barefoot INdoors
