This totally destroys all the pos. you can cut it smaller if needed The trick with ballet shoes is to use your street shoe size to fit the shoe, rather than going smaller. I have the Tile and the SpotyPal. Update, 11. It was a big decision for me spending £400 on such a private luxury but they are worth every penny. It?s otherwise a good product and works for what I need it for. My husband and I are training for Savage race and the shoes are what he needed. this stuff really helps! No Cons
