my calf muscles are ridiculously uneven in width.

I had suspected this for a while, but I got confirmation of it today. I was putting on some knee-high boots with a full-length zipper in the back, and I just could not get it over my left leg. The boot went on my right leg without a hitch. I seriously had to tug and stretch at the material to get that shit on my left leg. I've always had problems with getting boots on one leg, but I'm guessing my calves have only gotten bigger (asymmetrically still, natch) due to all the time I've logged on the treadmill and elliptical recently. This is getting out of hand. Interestingly enough, it's my left calf that is bigger, and I'm also left-handed. Is that even a thing?
