CYCYHEAT Heated insoles for women and men, Black, Size Medium — 4000mAh battery, cut-to-fit arch support

CYCYHEAT heated insoles are rechargeable, cut-to-fit footbeds with arch support and a 4000mAh battery that deliver adjustable warmth for everyday cold-weather comfort.

These battery-powered insoles combine thin, flexible heating elements with a lightweight 4000mAh pack so you can add controlled heat to most shoes without bulk. They warm up quickly, offer three temperature settings, and can be trimmed to fit inside boots, sneakers, or casual shoes. With an upgraded fast-heating element and clearly stated run-times per heat level, they’re built for long indoor days and casual outdoor use rather than extreme endurance sports.

How fast do these insoles heat, and how long will a charge last?

The upgraded heating element reaches noticeable warmth in under 30 seconds after a long press of the control button, letting you feel heat almost immediately. Run-time depends on the heat level: high offers the shortest duration while low gives the longest, so you can trade heat intensity for longer battery life.

• Quick heat-up: under 30 seconds with the 2025 upgraded heating element.
• High (approx. 130°F / 50–55°C): 4.5–5 hours of warmth.
• Medium (approx. 120°F / 45–50°C): 6.5–7 hours of warmth.
• Low (approx. 113°F / 40–45°C): 9.5–10 hours of warmth.

Can I fit these insoles into my shoes and how do I size them?

Yes — the insoles are designed to be cut to match your shoe size and feature arch support for everyday comfort. Trimming follows standard insole guides: cut gradually and test-fit frequently to avoid overcutting. The slim battery pack is small and light so it won’t significantly alter shoe fit when positioned correctly.

• Cut-to-fit design: trim along printed size lines to match shoe length.
• Arch support integrated for improved comfort in daily wear.
• Ultra-thin 4000mAh battery (0.19 lbs) to minimize shoe bulk.
• Not intended for intense outdoor sports or extended heavy-duty use.

What power and charging features does the battery offer?

The included 4000mAh battery uses a 3.7V, 2A DC interface and charges with the supplied 10W adapter in roughly 3–4 hours. It’s engineered to be lightweight and compact, making it easy to carry spare batteries or swap packs between shoes when needed. Follow the connector guidance to avoid incompatible replacements.

• Battery capacity: 4000mAh with 3.7V 2A DC connector.
• Fast charging: full charge in about 3–4 hours with the included 10W charger.
• Portable size: 3.2 × 1.7 × 0.6 inches and 0.19 lbs per battery pack.
• Run-times vary by heat level—choose settings to extend use.
