I had painful contusions on my instep from kicking elbows in TKD sparring. I wore these over the normal sparring foot gear (the kind that fit snug with toe holes cut out), and they allowed me to spar while my instep was healing. They also have kept my foot bruise-free ever since (even though I continue to kick elbows!)  

I have been using these for about a year for iaido training. My feet are bony and it really hurts when I sit in seiza position. These make it much more comfortable and I have no trouble at all going to seiza. I highly recommend these guards if you experience similar pain.  

I ordered these in-step guards and have been wearing them for my training in kickboxing and grappling. I also have a crack on my in-step, but ever since I have been wearing them, it feels like I have a new foot. It is amazing. Nice, comfortable to wear, light and great price.  

I just recieved this product, but I am already getting benefits from it. The guards are incredible for both sparring and bag use. Much more comfortable than bulky foam shoes and just as effective.
