This is a decent product that does what it's supposed too; although at retail it should be about third of its current price. It's composed of memory foam, a hard plastic base, and cushy exterior fabric. That should cost all of a few dollars to produce in China.

I bought these because I lift weights and they are hard on my foot arch; I also live in a house with hardwood floors. These are great solutions for both issues.

Note that if you have wide feet, this product isn't for you. I have a normal sized foot and the bases are just wide enough to conform to my feet. Also note that if you live in a cold climate and want to wear these with socks, you may be disappointed. Because the footprint is so small, your feet will slip out continually while wearing socks. If you wear them without socks, this doesn't seem to happen because there's more grip.

This would be a better product if: the cost were cut by 1/3, the bases were wider, and if the bases had more of a contour to hold the foot and prevent it from slipping off its base.
