Rooster Hot Socks - 0.5mm Titanium Neoprene

Add warmth without bulk. Rooster Hot Socks use a thin 0.5mm titanium neoprene layer to reflect body heat back to your feet. Wear them under your usual boots for an instant insulation boost — layering beats thickness for comfort and feel.

What makes these socks good

• 0.5mm titanium neoprene - reflective layer returns radiated heat to the body for extra warmth.
• Ultra-thin profile - fits under sailing/SUP boots without changing sizing or feel. 
• Layer-friendly - pair with Rooster PolyPro Socks for maximum warmth in cold conditions.
• Easy care - hand wash in warm soapy water; air dry.

Where they work well

Winter SUP, dinghy and keelboat sailing, coaching on cold decks, and any session where you want warmer feet without adding a thicker boot. Layer inside neoprene boots or drysuit socks for a noticeable heat bump with minimal bulk.

Materials & technical details

• 0.5mm titanium-impregnated neoprene (reflective layer) 
• Thin, flexible construction for use as a liner
• Designed to be layered with PolyPro Socks for extra warmth
• Hand-wash; air-dry care instructions

Fit & sizing

Snug, liner-style fit. Choose your usual sock size; the thin 0.5mm profile is designed to sit comfortably inside standard watersports boots without altering fit. For very cold days, wear over PolyPro Socks before putting on boots.

Care guide

Rinse after use. Hand wash in warm soapy water and air dry out of direct heat. This preserves the titanium layer and elasticity.

FAQ

Will they make my boots feel tight?

No - at 0.5mm they’re designed as a liner to add warmth without bulk. 

Do they work with drysuit socks?

Yes. Use Hot Socks as a liner with PolyPro underneath for extra insulation before your outer boot.

How do they keep feet warmer if they’re so thin?

The titanium-impregnated layer reflects radiated heat back toward the skin - like a survival blanket - boosting perceived warmth.

Our take

Simple, effective and low-bulk. If your winter boots are warm but not quite warm enough, Rooster Hot Socks add the missing layer without changing the way your footwear fits.
