Materials And Design

Want to know which materials make these socks waterproof? That’s what we’ll explore in this section.


The Sealskinz Waterproof Socks are made from a mixture of synthetic materials. They feature a composite outer fabric that consists of polypropylene, nylon, and elastane. The interior of the socks is made from Merino wool, acrylic, polyester, nylon, and elastane, for maximum performance.

The outer layer of the socks is made from materials that have excellent water resistance, but the inner layer of the socks is made from materials with better breathability. The interior of the socks has the highest percentage of Merino wool, which is one of the best materials for socks because of the great breathability, moisture control, and odor resistance.

There’s also a waterproof membrane between these two layers and it’s the main reason why the Sealskinz socks are totally waterproof. The membrane can transfer the moisture from the inner layer onto the outer layer, but it doesn’t work vice versa.


The Sealskinz Socks are perfectly suitable for warmer temperatures because of their excellent breathability. They have a high percentage of merino wool in the interior of the socks, which is the most important layer because it’s the one that’s always next to the skin. Merino wool is a breathable material with excellent odor resistance, and it’s the main reason for the great breathability of these waterproof socks.

However, it’s important to note that these aren’t as breathable as regular socks, especially if you pair them with thick hiking boots. They’re best for cold conditions, but they can work for warm weather if you pair them with lightweight and breathable footwear.

The Sealskinz Socks are completely waterproof, which is as insane as it sounds. The socks will keep your feet dry even if you walk right into the ocean, but they don’t promise to keep your feet warm.

You won’t get your feet wet in these socks, but if you walk through the water the outer layer of the socks could absorb some of the moisture. The water won’t leak through the membrane, but the issue is that the socks will get cold, which could in turn make your feet cold. Keep that in mind, especially if you’re looking for waterproof socks that are suitable for cold weather conditions.

Comfort And Sizing

How do the Sealskinz socks fit and are they as comfortable as regular socks? That’s covered in this section.


The Sealskinz Socks aren’t quite as comfortable as normal socks, but that’s mostly because they feel different. They’re also thicker than regular socks, so they might not fit very well with your favorite hiking footwear, especially if you’re used to a snug fit on your boots.

It’s worth noting that this mid-length sock has added support for a more comfortable fit. Both the instep and the ankle are elastic, so the socks don’t feel too tight. But because of the waterproof membrane, they can never be as elastic or as comfortable as plain socks, so keep that in mind.

Another important feature of these socks is the Y-gore heel construction. This provides a more secure and comfortable fit, while the flat seam of the hand-linked toe closure prevents rubbing and minimizes the chance of blistering.

It’s also worth noting that these socks have internal silicone grips around the ankles, which help the socks stay up no matter how much you’re moving around. This helps avoid any bunching, and it even minimizes the chances of water getting inside the sock through the upper openings.


The Sealskinz Socks are available in four sizes – small, medium, large, and extra-large. The brand does provide a handy sizing chart so it’s easy to figure out which size you need, but it’s worth noting that these don’t fit quite the same as normal socks.

They’re thicker than normal socks plus they’re mid-length, so they do run a little bit small. If you’re between sizes or at the higher end of a size, it’s better to size up for a more comfortable fit.

Value For Money

The Sealskinz Socks might look like conventional socks, but they’re certainly not priced like a regular pair. These are expensive, so it’s completely normal to ponder whether or not they’re worth the money.

If you really need a pair of waterproof socks, they’re worth it simply because you don’t have many other options. A waterproof sock isn’t exactly an easy item to manufacture, plus these socks are made from high-quality materials. They’re worth the money if they’re exactly what you are looking for and if you want wet feet to stop being a problem during your adventures.

Should you get the Sealskinz Waterproof Socks? If you desperately need a pair of socks that will keep your feet dry no matter what, you should consider buying them.

These socks are exactly what they promise to be – a pair of socks that is thoroughly windproof and waterproof. They don’t promise to be incredibly breathable, stylish, or insanely comfortable, and they’re not. They’re also not average, everyday socks, and if you’re just looking to upgrade the socks you wear on a daily basis, they’re not the right fit.

But if you want something that will help you deal with stream crossings and leaky waders, the Sealskinz waterproof socks are amazing. They offer extra protection from wet conditions with a waterproof membrane as a middle layer between a soft breathable interior and warm exterior.
