The socks, available in five sizes (from 31 to 47), are made in Italy; they are made of a comfortable material with 25% merino wool. The shaft is very long, so that depending on the length of your leg it can be uncomfortable in the back of the knee. The packaging highlights various features such as the shin protector and the knitted ring bandage to support the metatarsal bone.



There is no battery compartment; the battery is buttoned in and then the sock waistband has to be folded over to hold the battery firmly in place. This is of high quality and consists of two parts with an elastic intermediate piece so that it can adapt to the shape of the leg. The button on the battery can be operated through the sock if you don't want to use the app.

With Lenz, the heating element covers the entire toe area from top to bottom. However, the heating power is very low - it is hard to understand why there are nine levels. These are switched on via an app, and you have to register before you can use them. The workmanship of all components is high quality. The batteries are attached with snap fasteners as usual; the positioning of the cable in the sock is a good solution, as it doesn't get in the way anywhere.

The good wearing comfort is offset by the relatively low heating output. Nine levels make little sense in this case.
