I'm looking for some advice on road race boots. I've been racing supermoto for a few years now and have been wearing motocross boots for that and for general dual sport riding. I haven't had any problems with fit. This year I'm going to race minis and I want a pair of road race boots. I tried on a couple of pairs at the motorcycle show today and I couldn't get them to zip up past the ankle. Any suggestions on which brands fit a larger calf?
