My crews experience with them... Your feet will still eventually get cold with a pair of boot gloves on. It just takes a longer time to do so.
Once you take a break and need to warm up, take them off inside the lodge as then the neoprene will help keep the cold in. Also, don't put them on in the lodge or in a location where you have to walk across a non snow surface before clicking into your bindings, as walking on those more abrasive surfaces wears out the strap that goes across the sole of your boot more rapidly....
One final thing, especially for Glenn and Mrs. Glenn's humor sake... Boot Gloves don't make you nearly as cool as "neoprene butt guy" items!! :lol: (It's an old inside joke from Glenn and Mrs Glenn's Mount Snow days.... )
LOL! Do you still have that pic of him I took on Thanks Walt? That guy is a legend!
