Heat sock 5.1 toe cap slim fit

Heated socks like the Lenz Heat Sock 5.1 provide lasting warmth in the toe area and thus ensure a comfortable wearing experience – especially in cold weather. The heating function supports overall comfort and keeps feet pleasantly warm.

Wearing heated socks while sleeping is not recommended. The socks are designed for active use – such as winter sports, hiking, or outdoor work. During the night, lack of movement may cause heat buildup, which can reduce comfort. Alternative heat solutions without active heating elements are better suited for nighttime.

Lenz heated socks, including the Lenz Heat Sock 5.1, are powered by lithium packs. Charging time varies between 5 and 11 hours depending on the battery, and the fast-charging function is even quicker. Exact information can be found in the respective battery description. After charging, several heat levels are available depending on personal preference.

The slim-fit version was specifically developed for narrower feet. Compared to the regular version, it differs by its slim cut in the foot area. It fits closely to the foot, keeping the warmth directly at the toes – without pressure points or chafing.

Yes, the narrow-cut heated socks also feature Lenz’s patented Toe Cap® technology. They heat the toes from above and below via the lithium batteries without restricting mobility. The only difference is the cut – not the heating power or functionality.

Yes, the socks also fit into tight shoes and have been specially designed for narrow feet. The slim cut in the instep and heel area ensures an excellent fit even in stiff ski boots or tight hiking boots. At the same time, the heating performance remains fully effective.

The heating of the narrow-cut heated socks can be adjusted directly on the lithium pack battery in three levels or steplessly via Bluetooth using the Lenz Heat App. This is particularly practical for changing temperatures or longer use.

The slim-fit sock is tighter in the midfoot area. This prevents creasing and ensures a snug, smooth fit. At the same time, they are easy to put on thanks to the stretch content.
