Recently acquiered some new MTB shoes from NW. On one shoe, left, I have pressure from, I suspect, the cleat screws. I have swopped the screws around (R/L) makes no difference. I also added an extra insole from an old pair of hiking boots cut down to just behined the ball of the foot. Slightly better but still a little pain after an hour of riding. I am not able to access the cleat insert in the shoe from inside the shoe w/out cutting the piece under the insole out. Never had this issue with all my previous Carnacs (3 pairs). Any ideas?
