Foot sniffing is more common than you would think. The problem is that we need a full day of walking around in our running shoes to get that odour you love so much.....I have had to turn foot sniffers down because I just did not have time to get my feet into the condition they enjoy. I have lovely feet, high arch, well pedicured and nice toes but they rarely have an odour......someone should invent a foot cream that smells like sweaty feet I would buy it by the gallon.
