Warm feet - General Tips
A lot of the “Hands” tips are also about keeping YOU warm and happy first, and the same is true for your feet. Feet are harder to manage, and seem to get seriously cold more often.
I’ve never seriously frozen a finger, but I’ve frozen my feet at least twice to some extent, and have to work harder to keep them functional than my hands most days.
Realize that keeping your feet warm takes action on your part. It won’t just “happen” with one set of clothes or approach, you’ve got to be flexible with the environment, think ahead and act regularly to prevent misery in the future. It’s a war of many small battles, not, “My feet are really cold, doh!”
Cold feet start primarily when your core temp drops and your body decides to sacrifice the peripheral bits such as feet and hands. So don’t let that happen!
Control your core temperature to keep your feet warm. Have a light “moving but not sweaty” outfit and a “standing almost bivy” outfit that will keep you warm even if you’re standing around for an hour or so in the temperature you’re out in that day.
The difference in body heat output while moving vs. standing is massive, far more than peeling a few “layers” can deal with. If you just open the Goretex vents on your jacket you’ve done nothing useful. Take it off.
Layers are for onions and cakes. We need to think more “raging furnace while moving” vs “standing sleeping bag.”
Move in the least amount of clothing you can for the elements you’re in. You can move in less than you think mostly. Most people can run at -30 with running shoes on if they are moving hard enough. You’re a furnace, if you’re moving. Move, dress to stand, or freeze.
Test this in a low consequence environment, like hiking fast near your home/car on a cold day for an hour or so. Dress lightly at first. Once you're moving and body temperature is up, you may be pleasantly surprised at how little clothing you need.
A “standing” outfit means a big jacket, insulated pants, maybe mitts etc. Your “moving” outfit may be nothing more than a thin synthetic, or it may be close to your “standing” outfit if your output level is low. When I coach XC kids skiing I get laughed at for my puffy pants and jacket, but kids move so slow I have to totally overdress or I freeze.
Warm Feet: Specifics
Feet are big compared to hands. They take longer to get cold, and longer to warm up. If you start a day with cold feet you’re starting with a problem.
Unless you’re moving fast for 20 minutes or so right away you’re going to have cold feet until you do, or maybe for the day. So start the day with warm feet.
I don’t put my boots on while driving to climb or ski for this reason; my feet get cold sitting at my desk, as there isn’t enough blood circulating to keep them warm. Most of the time there isn’t enough warmth in the back of a car to keep your feet warm either, and they can actually get really cold. Oddly, some people think the exact opposite, and that’s OK too, but think about it. If your boots are really warm and you are too then your feet will sweat in the car, so make sure you keep your feet dry for the ride. Keep your boots in the car, not the back of the truck or trunk. Crank the heater and warm ‘em up on the drive.
If your feet are cold you have to get your core temperature up, and you have to circulate blood through your feet. This means moving, not just adding insulation! If your feet have gotten cold you will have to “overdrive” your body to pump enough blood through your feet to warm them up.
It takes about five minutes of going hard uphill to get the blood really pumping through your feet, and another five or so for them to be truly warm. Or 200 squats and 100 “leg swings” on each leg if you’re standing at a belay. Anything else won’t work.
Constriction on your feet is terrible in winter. If you stuff your boots so full of socks that they are tight on your feet, I guarantee you will be cold. Leave room! If you crank your ski or climbing boots down and then don’t loosen them you will get colder feet. Loosen your boots at belays or when resting, the difference can be amazing! If you have to bivy then loosen your boots right off. It may save your feet.
