Do Bigger Winter Shoes = Different Muscles
I have ridden about 5000 miles year. It is my first winter. I'm trying to learn to dress right. Just when the combo is right, it drops another 10 degrees. So for the last two weeks, I have been wearing a new pair of spd shoes in a size 40. I normally wear size 38. They don't slip off my heal, and I wear two pair of wool socks. The extra room appears to be in the toe area. Also wear Pearl Izumi boot covers. It made a lot of difference with my toes staying warm. I have a Lemond bike and it seems I use the muscles on the outer thighs and my butt to ride usually. Now my quads in front about 1/2 between the knee and top of leg are sore to the touch. Does anyone else have this problem when they switch to their larger winter shoes, or am I doing something wrong? I haven't added any additional sports, and I have noticed my average speed has dropped from 17-18 to around 14-15.
