I'm not really a fan. Broke the BOA on the third day. Lower BOA cables are too short so they restrict your foot from coming out of the boot easily when you are taking them off. They never stay tight because the BOAs pop loose all the f-ing time, and the boots are overall pretty soft and low for my taste. I've gone back to riding my malamutes.
But hey, they are light and have a smaller footprint than most.
