These are the heated socks that warm the whole foot from heel to toe. Only available from Hammacher Schlemmer, their thin metallic fibers are embedded between the fabric’s shell and liner to evenly distribute heat across the entire sole—a vast improvement upon lesser models, whose meager lumpy heating elements often scald the toes but leave the rest of the foot cold. These superior socks have three heat settings and quickly reach temperatures up to 135° F on high, and their lithium-ion batteries provide up to 2 1/2 hours of warmth on high (or 6 hours on low). The thick socks are woven from a cozy, anti-bacterial bamboo with a terry interior for comfortable flexing and walking. Machine washable; line dry. Batteries recharge in 4 1/2 hours with the included AC adapter. Light gray. For a snug fit, order one size down. Size L (Men’s 9-10; Women’s 10-11). (3 oz.)
