Because waterproofed shoes are fantastic for when the sky decides to unexpectedly dump water on you. And you're walking to your dorm. And you still have many many blocks to go. And there are puddles. Big ones. EVERYWHERE. Wet feet suck, my friends. I know there is also waterproofing spray available on the TOMS website, but I feel like this method would allow you to waterproof more shoes at a lower cost.
