on the science channel.. they were talking about making sneakers.
one of the factoids that was spat out... says there are about 250000 sweat glands on the feet. more per square centimeter than any other part of the body.
plus.. the went on to say that sneakers need excellent breathing material because in a day, ones feet can produce a cup of sweat.. that is a lot of water!!!
seen a woman wearing those plastic cinderella type pumps.. she was sweating up a storm.. wonder if at the end of the day she felt she had sweated a cup of sweat...
here is a pic to show ya what i saw that day.. (way back when i tried to be a candid photog but failed.. she saw me.. asked. and with my explanation.. got these pics)
