I have very flat feet and would have extreme pain for a day or two after doing TKD.  With these shoes, I immediate felt a huge difference and I know I can do TKD for years now!  Because of the different material on the sole, it has taught me to rotate better on my feet and allows me to be more aggressive with my actions!  This was the best purchase I ever could have dreamed of for TKD.<br /><br />If you have arch problems or pain, buy these shoes, you won't be disappointed.
