If you decide to get a heel protector Mugu-san, order a few to try them out. A heel protector can make you fall if you get the wrong one. I had ordered two, and I kept only one. The other was too fat and thick around the heel and nearly made me fall, but the other was slimmer and strong, and I didn't go sliding all over so I kept that one(The one I used at practice in Dec.). Plus, I can't feel the wood floor. It's comfy, but I prefer fumikomi without it even though I have to wear it. So, be careful what you get. The last thing you need, is a fall thanks to a foot protector. Kaoru
