Query: Great for Shoes

I got this for use in myVibram Fivefingers TrekSportand buy did it work wonders. My girlfriend stopped threatening to throw away my running shoes and started stealing my Kiwi when I wasn't looking. Takes a little getting used to, to find the right angle to hit the whole shoe, but once you've got it; you're all set.
