Maybe Santa will bring me a heated boot bag... but for now the plan is cost effective microwaved bean bags. Two Mountains I usually ski are 20 minutes and 1 hour away so the warm (bean)bags will work. BTW I am not totally 'cheap' just trying to be wise about equipment decisions for a 73 year old. Plus adding in lift tickets and equipment for a grandson and the sport can get $$$$ in a hurry. BUT I did not buy any new (or used) golf equipment this year so I feel entitled to minor splurges....If you have grown accustomed to instant response and complete control of a stiff close-fitting boot; you won't want to give that up.
As a control freak who was forced into new boots due to cold feet caused by diabetes-related poor circulation, I can relate.
Previous boots were ultra stiff custom fit foamed boots with custom kork insoles from the dark ages. I delayed the transition with boot heaters. That solution did nothing to help with getting in and out of the boots. A hair dryer was needed to get out of the boots (before I had a hair dryer and access to electricity for it, I recall having to stick by boots under the car heater for 20 minutes - even as a young man).
New boots were Mach 1 MV 120s. Much easier on and off with stock liner, but stock liners way to squishy for my control freak tendencies. Put in custom foam liners. Boots are stiff and difficult to put on and off. I use the hair dryer on cold days (below 0F).
But here's the thing! I bought a heated boot bag. The bag makes putting the warm boots on EASY! Even with the stiffer liners.
