Some of us stop skiing earlier than we should when our hands get cold. For others, quitting starts with feet. After trying sweaty socks, inflexible liners, expensive electronics, and homeopathic remedies, it may be time for a simpler solution. Yaktrax toe warmers are air-activated packets of magic that add just enough heat to get you through a long day. You’ll find even more benefit when paired with the other low-tech solution: boot gloves. The thin construction and adhesive backing allow you to sneak the heater in between your sock and boot liner for up to 5 hours of blissful heat. A light adhesive helps to keep the packets in place. Average temperatures of 105°F are warm, but not unpleasant, and allow for continued fun in the mountains no matter the temperature. Two warmers per packet.
