MERINOS wool socks with looped inside featuring 3 technical concepts:
Ergo Tech: guarantees optimal control of your movements: 3D knitted heel, heel and toe reinforcements, "soft" edge at the top of the sock to fit all calf sizes, size adjusted to the foot to get a perfect fit.
Optimal adaptation to the foot: tightening of the arch and malleoli for a precise fit
3-layer system: Three-layer knitting: the central polyamide weave ensures strength, dimensional stability and moisture transfer to the outside. This weave forms the backbone of the product.
The outer layer is made of thermo-regulating material and provides protection against the elements: it is a thermal shield. The inner layer is a cushion that provides cushioning, comfort and thermal regulation.
