We hear this often, especially when the weather turns unusually cold. Here a few ways to have warmer feet on the slopes.
Boot heaters and heated socks (and other heated items such as gloves and jackets). These work well and are considered essential equipment by many skiers. While boot heaters have been considered the industry standard for many decades, the majority of my high end clients now seem to prefer heated socks. Also, heated socks can be used without ski boots....
Boot Glove. This is a neoprene product that goes over the top of the boot. They definitely improve warmth and I have even had some clients use boot heating packs under them.
Dry socks and dry liners. Clean socks are much warmer and more comfortable than used socks. Many serious skiers clean their socks in a sink when a washer is not available. Dry liners require either a boot dryer or removing the liner overnight. Be award that boot dryers should not get over 120 degrees F, and should only be run an hour or two. The cylinder (cigar) shaped boot dryers can damage custom footbeds.
Heated boot bag. Great product but needs to be used with care. Good at drying boots a making them warm before skiing, but should generally only be used at low heat and for no more than an hour. Many racers use these because heating the shell makes the boots far less difficult to get on in the morning. But don't run these overnight!
Ski boots that come with heaters. Actually, we have seen some problems here. The main issue is that they typically install the battery behind the calf, which tends to cause fit problems. So far we are recommending getting heated socks or aftermarket boot heaters.
