I have started having issues with my feet. After 15 plus or so my feet start to burn and go numb. Have moved my clips on shoes back a fraction and that helped for awhile but went 55 miles today and had to stop a few times to let feet rest. The bike shop said to make sure the sole wasn't bending...not bending so now what? I bought some gel insoles today so I will give that a try. Any other help would be appreciated.
