I wll add, using a heated boot bag allows you to start the day with a boot thats warm in the core, extending the day a bit.
Cold toes are no fun. Last season I purchased a pair of the Lenz heated ski sock. Bought the thinnest version they offered. I had to send them back due to their being just thick enough to cause my feet to go numb in the boot. I never took them out on the slopes; only tried them on for awhile in the condo (up at Jackson) to see if they would indeed fit . I suspected they would not help me out since they were not thin enough.
This year I am headed up to Big Sky, and boy, would I love to have some warm toes ALL DAY LONG. Now I will have to think about those boot heaters. But again, I wonder if even those would add too much volume in my itty bitty boot. (Low volume, 21.5)
This also makes getting tight-fitting ski boots on a whole lot easier!I wll add, using a heated boot bag allows you to start the day with a boot thats warm in the core, extending the day a bit.
