I realize that it's an essential part of the summer experience...like your ice cream cone dissolving into a sticky mess before you've managed to consume a quarter of it...or your next door neighbor who practices for American Idol...in front of his open window...naked...at random times of the day and night...but why is it that you can change shoes no less than three times on a summer day only to discover that each pair will rub (and therefore cause agonizing pain) to a different part of your foot?

It's a test of endurance...a Japanese game show where only those impervious to blinding pain survive...a summer ritual...
