Staying warm in the water makes the biggest difference to how long you can stay out and how much you enjoy your session. Whether you are diving off the South Coast, surfing in Cornwall, or heading out on a paddleboard along the Jurassic Coast, the right wetsuit boots help keep your feet comfortable and protected. With so many designs, thicknesses and soles available, choosing the right pair can feel a little overwhelming. This guide breaks down everything you need to know, helping you pick the wetsuit boots that suit your sport and your style.
Why Wetsuit Boots Matter
Cold feet end sessions early. Once your toes lose feeling it becomes harder to balance on a board, control your fins, or move around safely on slippery decks or rocky shorelines. Wetsuit boots provide insulation, grip and impact protection. Thicker boots offer more warmth while thinner boots give you better feel and flexibility. The trick is matching the right boot to the right activity.
Choosing the Right Thickness
When browsing wetsuit boots you will see thicknesses ranging from 2mm to 7mm. Each level has its ideal use.
2mm to 3mm
These lightweight boots and socks are ideal for warm water, summer conditions or travel. They are also popular with snorkellers and freedivers who want minimal bulk. The Mares Equator 2mm Wetsuit Sock is a great example, offering comfort without restricting movement. It is a firm favourite among holiday divers heading to warmer destinations.
5mm
A versatile middle ground for UK waters. 5mm boots work for diving, surfing, kayaking and SUP. They balance warmth with flexibility. The Mares Classic 5mm Dive Boot is a strong all‑round choice, offering robust construction without feeling stiff.
6.5mm to 7mm
Ideal for winter. These boots provide dependable insulation for cold‑water diving or year‑round watersports. Heavier and more structured, they are built for durability and warmth.
Split Toe or Round Toe?
Split toe boots create a separation between the big toe and the rest of the foot. This improves balance and board feel, making them ideal for surfing or SUP. Round toe boots keep all toes together which retains more heat and often feels more comfortable for diving or general watersports.
Wetsuit Boots with Zip vs Pull‑On Styles
Many divers appreciate wetsuit boots with zip because they are easy to get on and off, especially when paired with a thick winter wetsuit. Zipped boots also tend to offer more structure around the ankle which helps when walking over rocks or using open‑heel fins.
Pull‑on styles are favoured by surfers and paddlers who want maximum flexibility and minimal water flushing. These lighter boots hug the foot more closely, improving balance and board control.
If you prefer zipped boots, the Mares Classic 5mm and the Mares 6.5mm Flexa models are popular choices thanks to their sturdy zips, comfortable linings and reliable grip.
Choosing Boots for Your Sport
Diving
Diving demands durability. You need thick neoprene and a hard sole for moving across slipways, decks and uneven shorelines. Wetsuit boots with zip are ideal here. Mares wetsuit boots are particularly strong in this category thanks to their reinforced toes and rugged soles that work perfectly with open‑heel fins.
Surfing and SUP
Feeling the board beneath your feet is essential. Surfers rely on lighter soles and a snug fit. A split toe style helps with control and reduces slipping inside the boot. Most 5mm surfing boots are warm enough for UK use throughout spring and autumn.
Kayaking and Canoeing
Flexibility matters when sitting in a cockpit or kneeling. Choose a softer sole that bends easily. The right pair provides warmth without compromising comfort over longer sessions.
Dinghy Sailing
Grip and ankle protection are key. A 5mm boot with a reinforced sole helps you move confidently around wet decks.
Ladies Wetsuit Boots
Fit matters and many women prefer a narrower cut that supports the foot without excess room. Ladies wetsuit boots often follow the same thickness guidelines as unisex boots but are shaped to reduce flushing and improve comfort. Mares offers several models designed with female divers in mind, providing security without feeling bulky.
Mens Wetsuit Boots
Mens wetsuit boots usually feature a broader fit and slightly more space through the instep. From lightweight 3mm travel options to rugged 6.5mm boots for cold‑water diving, men’s ranges are designed to balance warmth with durability. Mares’ men’s boots are known for their robust construction and dependable grip on wet surfaces.
Childrens Wetsuit Boots
Keeping kids warm is essential for happy days on the water. Childrens wetsuit boots are usually thinner and more flexible, helping younger users stay comfortable and confident. Look for easy entry, solid grip and a snug fit that stops water flushing in. Junior models from brands like Gul and Typhoon offer reliable warmth for family adventures around the UK.

Wetsuit Boots FAQ
For most of the UK year a 5mm boot offers the best balance of warmth and flexibility. Winter divers and cold‑water surfers often choose 6.5mm or 7mm boots for extra insulation. Thinner 2mm to 3mm boots are ideal for summer conditions or warm‑water travel.
Wetsuit boots with zip are easier to get on and off, especially when wearing thicker wetsuits. They often provide more ankle support which is great for divers or anyone walking over rocks. Pull‑on boots are lighter and more flexible which makes them popular with surfers and paddleboarders who want better board feel.
They should fit snugly without being painful. Your toes should lightly touch the end of the boot but not curl. Too much space leads to water flushing in which makes your feet cold. A close fit helps the neoprene trap a warm layer of water against your skin.
You can, but it is not always ideal. Diving boots usually have thicker soles and zips for durability and ease of use with fins. Surfing boots are lighter and offer better grip and sensitivity on a board. If you switch between sports often a 5mm all‑round boot can work well.

Rinse them in fresh water after use then leave them to dry in a shaded, well‑ventilated area. Avoid direct sunlight or radiators as they can damage neoprene. Turning boots inside out halfway through drying speeds things up.
Wetsuit socks are thinner, softer and designed for light protection or use inside fins. Wetsuit boots are thicker and offer better grip, durability and warmth. If you regularly walk across beaches, slipways or rocks you will need boots rather than socks.
