Heat Holders Maker David Doughty knows socks inside and out. After a career spent manufacturing them, he switched gears and began making his own in the garage. His inspiration? His son’s struggle with cold feet during a soccer game. David’s take on socks is plush, cushy, and up to seven times warmer than typical cotton socks. That’s due to the brushed yarn’s extra-long, cushiony pile that traps heat close to the body while wicking away moisture. What's best of all is how ultra-soft the socks feel. Cozy for indoors and hardy for outside, Heat Holders keep feet warm no matter where you walk.
