Built for all-day warmth inside your boots. Heat Holders® ORIGINAL™ socks are 7X warmer than a basic cotton sock — not a little warmer, not somewhat warmer, but a measurable 2.34 TOG rating that you feel the moment you put them on.

Every pair is made from a specially developed heavy bulk yarn with extreme thermal qualities. The inside is intensively brushed to create a thick, soft cushion of warm air that stays trapped against your skin. The result: feet that stay warm for hours, not minutes. Non-binding and diabetic-friendly — designed for comfort that lasts all day without pressure or restriction.

• 7X Warmer Than Cotton. 2.34 TOG thermal rating — the warmest non-industrial sock you can buy.
• Full Calf Coverage. Crew-to-calf length keeps warmth locked in — ideal inside boots, wellies, or tall shoes.
• Intensively Brushed Interior. Thick, soft lining traps warm air against skin; feels like wrapping your feet in a warm blanket.
• Non-Binding & Diabetic-Friendly. No tight bands, no pressure points — safe and comfortable for sensitive feet and circulation issues.
• Built to Last. Machine washable, durable construction — these perform season after season.

No More Cold Feet!®
