Lenz Heat 3.0 Sock Unisex

A spare pair for those longer trips, the Lenz Heat 3.0 sock is a unisex size to pair with your lithium pack for a fresh pair of socks while your other pair takes a break in the wash. Merino wool for warmth and moisture transfer is additionally treated with SOFTTEC®, an inner layer of high-tech yarns which provide itch free comfort for those sensitive to wool and added durability. Cold feet are more than just miserable, cold saps your muscle strength, and can lead to a 50% loss of muscle strength and control. As that cold migrates from your toes, to your foot, and up your calf, you're losing strength and ability along with comfort. And while you can take a cocoa break, that isn't how you want to spend half your day... indoors trying to warm your feet up. A pair of Lenz socks is designed to wear for several days without necessarily needing a wash, but on a long trip the ability to rotate socks, or rinse a pair out and leave them to dry, is a genuine pleasure, a luxury you'll appreciate every time you bump the heat on your feet and smoothly enter that next run.
