Not riding- specific boots, but I have a pair of "Danner" boots that I ride with, and they have large sizes (mine are 14 I think). They're the same boots the VPD wear - sort of like a combat boot, but completely water proof (goretex), warm (thinsulate), and comfortable to walk in. I've had em for 2 years, and love em. They sell them at "3 vets" which is near Cambie st. I believe. If you don't find the riding specific boots you want, look into these. good luck.
