Lenz HEAT SOCK 5.1 TOE CAP SLIM FIT Heated Socks: Targeted warmth and comfort for narrow feet

The Lenz HEAT SOCK 5.1 TOE CAP SLIM FIT heated socks are designed to provide precise warmth and a comfortable fit when you’re exposed to the cold, especially if you have slender feet and legs. Thanks to their Toe Cap® heating element, which wraps around the toes from above and below, they provide an even feeling of warmth across the front of the foot. Their slim fit ensures an ergonomic fit, while the technical construction is designed to reduce pressure points and maintain your comfort. Designed for demanding winter activities, these socks combine high-performance materials with a specialized design to help keep your feet warmer for longer.

Insulation and Targeted Warmth for the Toes

At the heart of the Lenz HEAT SOCK 5.1 TOE CAP SLIM FIT heated socks is Toe Cap® heating technology, a heating element that covers your toes from above and below to distribute heat where sensitivity to the cold is greatest. This targeted approach concentrates heat at the tips of your feet, providing comfort from the very first minutes of use. Thanks to compatibility with all Body Heat System lithium packs, you can adjust the heat level to suit your needs—either directly on the pack or via the free Lenz Heat app on your smartphone—helping you better manage your thermal comfort throughout the day.

The internal structure also features reinforcements at the toes and heel, as well as additional padding around the tibia and fibula, to minimize pressure points inside the shoe and improve heat retention. In practice, you’ll enjoy a softer feel in the areas under the most stress and support that promotes consistent comfort whether you’re active or at rest.

Comfort, support, and freedom of movement for narrow feet and legs

Designed for narrow feet and legs, these heated socks feature a slim fit that ensures a precise fit in your winter sports shoes. The ergonomic left/right knitting follows the natural shape of each foot, reducing creases and friction to preserve your freedom of movement.Enhanced elasticity at the calf makes them easier to put on and ensures consistent support along the entire length of the sock, without excessive compression—a feature you’ll especially appreciate during a full day outdoors.

A circular band across the instep further enhances the fit by minimizing slippage inside the boot. This helps keep the heating element in the optimal position over the toes and contributes to a comfortable, supportive feel while walking or during prolonged activities. This construction ensures a technical sock that stays securely in place while moving with you without causing discomfort.

Technical Materials and Moisture Management

The Lenz HEAT SOCK 5.1 TOE CAP SLIM FIT heated socks are made from a blend of 50% polyester, 15% merino wool, 25% polyamide, 5% silk, 3% spandex, and 2% polypropylene. This combination blends the warmth and natural properties of merino wool with the durability and resilience of synthetic fibers, making them ideal for regular use in winter conditions. The silk adds an extra touch of softness against the skin, whilethe spandex contributes to the sock’s shape retention and flexibility, ensuring good freedom of movement.

Merino SoftTec® technology optimizes this blend by combining the natural warmth and breathability of merino wool with high-tech fibers for itch-free comfort. In practical terms, this is designed to minimize irritation while facilitating the wicking of moisture away from the fabric. For care, these socks are machine-washable at 30°C, which simplifies their everyday use while preserving their technical qualities, provided you follow the washing instructions.

Practicality and Electronic Compatibility

Designed to integrate seamlessly with your gear, these heated socks are compatible with all Body Heat System lithium packs, allowing you to use the brand’s batteries if you already own them or to add more later. The heat can be adjusted either directly on the lithium pack or viathe free Lenz Heat smartphoneapp, allowing for more precise control of the heat intensity and quick adjustment to your current comfort level. This connectivity lets you adjust the heat based on your activity and weather conditions, without having to take off your shoes.

Additionally, the boots are machine-washable at 30°C, making regular maintenance easy—an important feature when you’re going on back-to-back winter outings. The combination of these practical features with the targeted heating design makes this model a technical ally for those who want to better protect their feet from the cold while maintaining good freedom of movement.
