ATAN Watersports Boots: The Definitive Guide to 3mm vs 6mm
ATAN boots are widely regarded as some of the best neoprene watersports boots available. Trusted by surfers, kitesurfers, windsurfers and wingfoilers, they’re known for warmth, durability and a fit that prioritises performance rather than comfort-store softness.
One of the reasons ATAN boots work so well is their simplicity. ATAN only produces two boot thicknesses: 3mm and 6mm. No unnecessary overlap, no confusing models — just two boots designed to perform exceptionally well in their intended conditions.
This guide explains what makes ATAN boots different, how to choose between 3mm and 6mm, and how to get the right fit for UK watersports.

Who Are ATAN?
ATAN is a specialist French manufacturer focused solely on neoprene boots and gloves for watersports. Unlike mass-market brands, ATAN takes a performance-first approach, prioritising fit, seam quality and long-term durability over seasonal trends.
This specialist focus is why ATAN boots feel different the moment you put them on — they’re designed by people who understand cold-water riding, not by marketing departments.
What Makes ATAN Boots Different?
- Snug, secure fit that reduces water flushing
- Excellent warmth for thickness without excessive bulk
- Strong seam construction in high-stress areas
- Good board feel for pads, straps and surf-style riding
ATAN boots feel like an extension of your foot rather than stiff footwear. This is why many experienced cold-water riders stay with ATAN once they’ve found their size.
Buying Guide: Choosing Between ATAN 3mm and 6mm Boots
ATAN keeps the decision simple by offering two thicknesses. The right choice depends on water temperature, session length and how cold your feet typically get.
- ATAN 3mm Boots: lighter, more flexible, and focused on board feel.
- ATAN 6mm Boots: maximum warmth for cold water and long winter sessions.
A correct fit is critical. A snug boot will always feel warmer than a loose boot of the same thickness.

ATAN Split Toe vs Open Toe Boots: What’s the Difference?
ATAN boots are available in both split toe and open toe (round toe) designs. The difference isn’t about warmth — it’s about feel, control, and personal preference.
ATAN Split Toe Boots
Split toe boots separate the big toe from the rest of the foot. This creates a more locked-in feel inside the boot.
- More control: Improved grip and feedback on the board.
- Secure feel: Popular with kitesurfers, windsurfers and strap riders.
- Better edging: Especially noticeable during powered riding and landings.
Best for: Kitesurfing, windsurfing, and riders who want maximum control and connection to the board.
ATAN Open Toe (Round Toe) Boots
Open toe (often called round toe) boots allow all toes to sit together naturally.
- Slightly warmer feel: Toes share heat more easily.
- Natural comfort: Often preferred by surfers and freeriders.
- Less restrictive: Ideal for longer, relaxed sessions.
Best for: Surfing, wave riding, wingfoiling and riders who prioritise comfort over locked-in feel.
Which Should You Choose?
If you ride powered, use footstraps, or value precise control, split toe ATAN boots are usually the better choice. If you prefer a more natural feel and slightly better warmth for long sessions, open toe ATAN boots are often the favourite.
Both designs use the same high-quality neoprene and construction — warmth and durability are determined far more by fit and thickness (3mm or 6mm) than toe style.
Why ATAN Fit Feels Different to Other Brands
ATAN boots are designed with a snug, performance-oriented fit. They often feel tighter when dry compared to mass-market boots — and that’s intentional.
- Less internal volume means less water flushing
- Better heel and ankle hold improves control and warmth
- Reduced movement helps the boot keep its shape longer
Many boots feel comfortable in a shop but loosen in the water. ATAN boots mould slightly once wet, then remain secure for the entire session.
ATAN Boot Sizing Guide
ATAN boots are designed to fit snugly. This is essential for warmth and performance.
- The boot should feel tight but not painful when dry.
- There should be no loose space around the heel or ankle.
- Your toes may lightly touch the end, but should not feel curled.
If you are between sizes
- 3mm boots: many riders size down for precision.
- 6mm boots: sizing up can help comfort for long winter sessions or wider feet.
