So last night after work I am reading cyclingnews.com and there is an article by KB about dealing with different pain problems on multiday mnt bike events. Oddly enough, he gives a cure for helping with hotspots. What does he suggest? Cork under the sole of for shoes.
That's pretty cool. It goes into detail as to why it works by helping push away heat build up that is caused from cleat to pedal contact. This has me thinking. Might have to give it a try if I can find some inexpensive cork.
