SPD cleats damaging mountain bike shoes Hoping you guys could help me. I recently bought SPD cleats and as mentioned in this forum I've been using spinning bikes to practice unclipping. 

I've noticed that my right shoe is getting damaged with the cleat. As in it is grinding into the sole of the shoe and scraping it. I am having difficulty unclipping this shoe.

Strange thin is I'm not having this issue with the left shoe. Ive tried various spinning bikes and I have the same problem.

I'm afrain I'm going to grind a hole into my sole.

Please help. :-(
Most probably you have not screwed it in tight enough. Cleats have to be screwed to the sole really tight.

Because the cleat is so small compared to your leg, there is a huge leverage being applied to it when clipping in/unclipping. If it's not tight enough, that's just what you can expect - it will move against the sole at pressure and grind it down.
