Do you know where your toes are going numb specifically? I.e., the inside of your foot versus the outside?

Based on my experience, numb toes usually has more to do with cleat placement than anything else. In some instances, there are some times where a simple cleat adjustment won't work and you need a cleat plate extender of some sort, but the majority of cases are usually just a few millimeters off.

I'll do my best to help virtually if I can.
