THE SOCK THAT DRIES FAST AND KEEPS YOUR FEET WARM — WET OR DRY

Born in watersports. Perfect anywhere feet get wet.

Thermal Flex Socks use the same Active Thermal Waterwear fabric developed by Sharkskin for divers, surfers and paddlers who needed warmth, flexibility and fast drying performance without bulky neoprene.

But users quickly discovered something bigger.

Anywhere people deal with wet, cold, uncomfortable feet, Thermal Flex Socks make a real difference — from bushwalkers and travellers to marine workers and outdoor crews.

Thin enough to wear comfortably inside boots or shoes, yet warm enough to noticeably improve comfort, they work wherever feet get wet.

From water to work. From boat ramps to bush tracks.

HOW THERMAL FLEX FABRIC WORKS IN SOCKS

Thermal Flex performance comes from a combination of advanced fabric technologies, not thickness or waterproof membranes.

• Ultra-high-density Lycra construction creates insulation while remaining thin, flexible and body-hugging.
• Durable Water Repellency is applied to the fibres themselves, not just surface coatings, so the fabric absorbs less water and dries extremely fast.
• Titanium nanoparticle infusion generates Far Infrared (FIR) energy, supporting thermoregulation and circulation.

The result:

• Socks stay warm even when wet
• They shed water quickly and dry fast between uses
• Feet warm up sooner once out of water
• Less wind chill after exiting water
• Greater comfort throughout the day

Unlike neoprene socks that stay wet and heavy, Thermal Flex socks are ready to go again quickly.

Warm in the water. Comfortable out of the water.

IDEAL FOR ANYONE WHO GETS WET FEET

• Diving & watersports
• Fishing & boating
• Kayaking & paddling
• Bushwalking & hiking
• Camping & travel
• Outdoor & marine workers
• Boat ramps & beach use
• Wet weather commuting
• Wearing inside boots or shoes in wet conditions

WHY PEOPLE KEEP USING THEM

Most water socks get used occasionally.

Thermal Flex Socks become the ones people keep in the car, at the door, and in their gear bag — because they solve the everyday problem of wet, cold feet.

Warm. Fast drying. Ready to go again.

Why Thermal Flex Works

🔥 Warmth Without Overheating

Titanium nano‑particles reflect your body’s natural heat back toward the skin, maintaining consistent warmth without trapping excess heat. Your feet stay warm, regulated, and sweat‑free.

💧 Water Repellent & Fast Drying

The DWR treatment causes water to bead and shed from the fabric. After full immersion, Thermal Flex Socks dry rapidly — perfect for multi‑session water sports or long work days in wet conditions.

🧦 Thin, Stretchy & High-Density

Unlike bulky thermal socks, Thermal Flex is thin, smooth, and extremely elastic. Ideal for wearing:

Under water shoes
Inside dive or snorkel fins
Inside neoprene boots
Under wetsuits for easier entry & reduced friction

No pressure points. No restriction. Just flexible, all‑day comfort.

💨 FIR Compression for Circulation & Recovery

Gentle compression combined with FIR technology helps support:

Improved circulation
Reduced fatigue
Faster recovery

Great for both in‑water performance and everyday wear.

Designed for Water. Useful Everywhere.

Ideal for:

Snorkelling & diving
Surfing, paddling & kayaking
Wearing under neoprene boots for extra warmth
Easier wetsuit entry
Cold, wet work environments
Travel, recovery, and everyday warmth

While engineered for water sports, many users will wear Thermal Flex Socks as a general-purpose warm sock thanks to their stretch, comfort, and circulation benefits.

Key Features:

Thin high-density stretch Lycra
DWR water-repellent treatment
Titanium nano-particle infusion
Far Infrared thermo-regulation
Fast drying even when soaked
Lightweight, flexible, non-bulky
Supports circulation and recovery

Thermal Flex is designed to be worn firm/fitted (not loose) on your body to take advantage of the compression and water repellence properties, the Far Infrared technology in the fabric, and to allow for unhindered movement through the water while swimming and/or during active water sports activities.

No other water sports garment gives as much warmth and flexibility for the weight of the garment than Thermal Flex.

For details see our size chart.

Thermal Flex Socks are designed and tested alongside Sharkskin’s professional thermal systems — engineered to perform where traditional socks fail.

Warm when wet. Comfortable when dry. Built to move.

At SHARKSKIN, we deeply care about the environment, as many of us are avid scuba divers and natural world enthusiasts. Our commitment to sustainability is demonstrated through five key company initiatives.

Solar Powered
We are pleased to announce Sharkskin’s new building is 100% solar powered.
Environmental Manufacturing
Sharkskin manufactures in its own factory, allowing us to strictly control waste and efficiency. We pack our orders effectively to reduce freight and waste, and we use cutting-edge technology to minimize material waste throughout the manufacturing process.
Biodegradable Packaging
We have transitioned to biodegradable packaging. Currently, 95% of our range uses this packaging, with a goal to reach 100% soon. All newly manufactured items will be packed in the new biodegradable bags, while items in stock will remain in existing packaging.
Australian Made
We are proud to announce that we have been accredited to use the official Australian made Logo. The official website states, “The famous ‘Australian Made, Australian Grown’ (AMAG) logo is the true mark of Aussie authenticity. It’s Australia’s most trusted, most recognised and widely used country of origin symbol, and it’s underpinned by a third-party accreditation system, which ensures, products that carry the logo are genuinely Australian”.
95% of our range is proudly Australian-made. Products that do not feature the "Australian Made" logo below the "buy now" button are not manufactured in Australia.
Built to Last
We believe in creating quality gear that stands the test of time and the harsh Australian conditions. This not only results in a better product but also keeps items out of landfills, reducing waste and environmental impact for the future.
