There's more to keeping your feet warm than increasing your insulation. Here are some things you can do to actually increase the warmth of your boots.
- Stay dry. Moisture conducts heat away from your body 25 times faster than air.
- Make sure your boots fit. A proper fit will ensure that your feet stay warm.
- Wear the right socks. A thermal wool sock over a polypropylene sock is the best combination. Thick socks can constrict blood flow to your feet, causing them to become cold much faster. Cotton socks will absorb moisture and keep it close to your feet, making them wet and cold.
- Don't expose yourself to extreme temperature changes. If driving, don't turn up the heat to stay warm in the car. It will only make it more difficult for you to warm up once you are out in colder temperatures.
- Let your liners breathe. When taking a break, loosen your laces to let perspiration evaporate. Take the liners out to dry them overnight.
- Carry extra liners to replace ones wet with perspiration.
- Add an insole. Stick a LaCrosse wool-felt insole between your removable liner and the bottom of the boot to absorb excess moisture and enhance warmth.
- Bundle up. If your hands and head aren't properly covered, your whole body loses heat faster. It's also important to layer your clothing, which help to insulate and trap warm air between the them.
