Is it possible to get warts this way? If so, is there anyway around it? I just thought of this today while watching people try on flip flops while barefoot at DSW. I also saw someone trying on regular shoes barefoot.....which I thought was crossing some sort of shoe-shopping etiquette line. I don't expect people to use shoe horns at discount/outlet stores, but I feel like people should at least wear socks while trying on loafers and lace-ups.
