Lenz 5.1 Slim Fit Heat Sock

All of Lenz’s Thermal Socks have been renewed. The leg parts of the socks are now even more flexible, now even bigger calves are not squeezed. Slim fit is thinner and more compact than the basic model at the foot. More flexible material completes the perfect fit. We recommend this especially for shoes where there is no room for thick socks. All thermal socks have Lenz’s patented ToeCap thermal elements above and below the toes. Heat elements are not noticed, and cannot be recognized by anything other than warm toes.
