I am a competitive dancer and I wear Amys After 5 brand. You can buy them at
amysafter5.com I use to wear out other brands within a few weeks but not these they last a long time. They are a fairly new brand but I find them to be more comfortable and made of better materials then even the top brands like supadance. And they are 1/2 the price of the top brands! (About $70) Plus my balance improved when I started wearing them. I defiantly recommend giving them a try.
