I like to go without socks when I can. There are some sneakers I have that I can do this with - probably because they fit me so well. I also wear orthopedic inserts. And finally, I have not (and the other people I live with have not) noticed any foul odors. There is something cool about a sockless sneaker experience. Not cool as in fashionable (though I'm sure at some point that was/is the case), just cool as in temperature. I wonder how people feel about a sneaker that you can wear without socks - no blisters, no foul smell (really no more foul than regular sneakers) and just more effificient - plus that feeling you get with you go without something (yes let your imagination run wild).
