I'm not interested in clipless pedals. I did purchase a pair of 5.10's for riding. Stiffer soles, stick to the pedals well. They're quite comfy, but I noticed yesterday after a few miles my feet began to ache. The ache went away after a few minutes of being off the bike. Since the soles of the 5.10's are stiffer than the Keen boots I had been wearing for the last month, I'm wondering if it's about having my feet in a new position. I'm hoping it's just a matter of breaking them in. Any thoughts?
