The arch support on these feels fine, but the rest of the insert falls short. The padding doesn't have provide enough support so after a few hours the heels and balls of my feet start to ache. Plus the insole fabric is quite slippery and my feet slide around on it in my shoes.<br /><br />And the rubber material these are made of literally stinks like chemicals and it never went away after several weeks. (Search these reviews for the word &#34;smell&#34; and you'll see several people reporting the same thing.)<br /><br />Overall the negatives far outweigh the positives on these inserts and I will not be buying them again. I prefer the Dr. Scholl's Tri-Comfort orthotics which provide much better relief in the heel and ball of foot, and they don't slide around or smell like chemicals.. I should have stuck with those, but I wanted to give this other brand a try to see if it was any better. It's not.<br /><br />PS - If you still want to try them out, you can buy these all day long at T*rget and W*lmart for under 10 rather than the high price being charged here. :)
