B Socks Rechargeable Heated Socks — heated sock for Women & Men, Unisex 6–10, 3 Heat Modes & Front-Instep Warmth

B Socks rechargeable heated socks are battery-powered crew socks with a front-instep heating element and three temperature settings designed to keep feet warm during cold-weather activities.

These electric footwarmers combine stretchy cotton-blend fabric with a removable 3.7V Li-ion battery system to deliver adjustable warmth where you need it most. Built for outdoor pursuits like skiing, hiking, hunting and ice fishing, they also serve as a cozy indoor option for anyone who routinely struggles with cold feet. The pair includes two 2000 mAh batteries, a dual charger for 110–220V, and a protective gift box for storage.

How quickly do these socks warm my feet and how long does the heat last?

The heating element activates rapidly so you feel noticeable warmth within about a minute after switching on. Heat duration depends on the selected power level: low extends runtime while high delivers maximum warmth for a shorter period. Typical use varies between roughly 3 to 6 hours depending on temperature setting, battery charge and activity level.

• Rapid warm-up: noticeable heat within ~1 minute
• Three heat modes: low (green), medium (orange), high (red)
• Runtime range: approximately 3–6 hours depending on setting
• Comes with two 2000 mAh batteries and a dual charger

Where is the heat concentrated and does the fabric stay comfortable?

Heat is focused on the front instep region of the foot for targeted warmth without bulk across the entire sock. The socks are woven from a cotton, polyester and spandex blend that stays soft and stretches to fit most feet comfortably. Even without power, the thicker knit offers passive insulation, and the heating lines are integrated to preserve a natural sock feel.

• Heating zone: front instep for focused warmth
• Material: cotton, polyester and spandex blend for comfort and stretch
• Passive warmth: thick knit retains heat even without batteries
• Designed to fit US unisex sizes roughly 6–10

How do I care for these heated socks and handle the batteries safely?

To protect the internal heating element, hand washing or a gentle wash cycle is recommended and the connecting wire should be secured inside the battery pocket before laundering. Never use the socks while wet and avoid prolonged use on the highest setting. Batteries arrive partially charged from shipping; fully charge both batteries together before first use and follow the included manual for charging and storage guidance.

• Wash recommendation: hand wash or soft cycle; tuck wire into pocket
• Safety: do not use while socks are wet; stop if discomfort occurs
• Charging: charge both 2000 mAh batteries fully before first use
• Temperature caution: avoid extended use on the high (red) setting

What comes in the package and what color options are available?

The set includes one pair of heated socks with the thermal element installed, two rechargeable 2000 mAh batteries, a 110–220V dual AC charger, a user guide and a gift-ready box. A range of color combinations lets you pick a look that suits your gear or style, from neutral tones to brighter two-tone mixes.
