Finally — thermal socks that actually come in sizes 13–15. Heat Holders® ORIGINAL™ socks deliver 7X warmer than a basic cotton sock (2.34 TOG) in a proper extra-large size — not a regular sock stretched to fit, but a sock built from the ground up for bigger feet.

If you’ve been settling for regular “large” socks that are too tight, too short, and wear out faster because they’re over-stretched — this is what you’ve been looking for. Same advanced thermal yarn. Same intensively brushed interior that traps warm air against your skin. Same non-binding, diabetic-friendly comfort. Just finally in a size that fits the way it should.

• True Extra-Large Sizing. Crew length in Men’s sizes 13–15 — not a “stretched regular” but properly sized from the ground up.
• 7X Warmer Than Cotton. 2.34 TOG thermal rating — the same legendary warmth as the standard size, now in yours.
• Intensively Brushed Interior. Thick, soft lining feels like wrapping your feet in a warm blanket — no compromise for larger sizing.
• Non-Binding & Diabetic-Friendly. Extra important in larger sizes — no tight bands, no pressure points, no restricted circulation.
• Built to Last. Machine washable, durable construction — designed for season after season of wear.

No More Cold Feet!®
