5. Running Socklet
The socks are thick enough to provide warmth but are made of nylon and elastane to ensure movement in the sock feels natural. A Merino wool interior wicks away sweat and moisture from other sources. This results in a comfortable wear experience since feet never feel like they're soaking in water. Even with a waterproof design, the socks are capable of ventilating. An elastic specifically placed at the ankle provides support, too.
The lower height of the sock makes it a good choice for warmer weather, but it's high enough to keep the ankle protected from chafing and rubbing.
The socks are the perfect choice for runners who frequently train in wet conditions or just after a heavy rainfall. Puddles are no match for these socks. The material is waterproof and also keeps the wind at bay.

The Hydrostop design is ultra waterproof, but it should be noted that the design creates a seal that may become uncomfortable if worn for long periods of time.
The socks come up halfway on the calf which offers protection and comfort to the wearer.
The MTB Sealskinz socks are made of a special Hydrostop material which keeps water out from all angles. At the ankle, there's no need to worry about water coming in because of this technology. A seal is created to keep moisture out. There's also a moisture-wicking Merino liner.
The Hydrostop Sealskinz socks are mid-weight, so they provide warmth and padding. They are a thicker sock so be sure to try them out with your shoes to ensure you don't feel too snug inside your footwear.
- Keep feet very dry
- Provide exceptional warmth
- Not good for long periods of wear
7. Hiking Mid Knee with Helicase Sock Ring
The breathable Sealskinz hiking sock protects from water without sacrificing ventilation, so you get the best of both worlds as you enjoy the outdoors. A Merino wool interior keeps moisture and temperature controlled to ensure the comfort level of the wearer. The socks are a little thicker, so there's a nice bit of padding.
This particular Sealskinz brand sock features a knee-length cut which provides superior protection. A higher cut is a good choice for those heading out in very bad weather, trekking in deep snow, or those who just want extra protection from the wind and other elements.
Naturally, like other Sealskinz socks, the Hiking Mid Knee sock provides exceptional waterproofing. The sock also protects from wind.
These Sealskinz hiking socks are a little thicker than some others. They are rated three on the Sealskinz thermal rating scale. This means they're a good option for hikes in cooler weather.

They are breathable and protection with a soft exterior that feels great to the touch. Flat seams keep blisters at bay, and the elastic ankle construction keeps the socks in place.

The Merino wool lining is a great help since it regulates temperature by wicking moisture all while ensuring warmth.
The socks are rated a two on Sealskinz's thermal rating scale. Despite their categorization as a thin sock, they are more close to mid weight.
- Soft feel
- Some sizing issues
9. Trekking Thick Mid
The socks are made of a combo of nylon and elastane with a hydrophilic layer that keeps moisture away from your feet and into the sock. Inside, there's a Merino wool layer that promotes a warm and dry environment. The thicker design of these socks ensures the wearer stays both warm and comfortable even when it gets cold or very wet.
The socks are a mid-calf length which provides a bit more protection than your standard ankle length socks. This makes these a good option for wearing inside winter boots. A little extra length keeps more of your foot and leg protected from puddles and the elements.
There's no surprise that these are another waterproof (and windproof) option from Sealskinz. The thickness of the sock might lead one to believe that moisture would make things heavy and cumbersome but that's not the case. Instead, the Merino wool and hydrophilic layer keep moisture away from the body, keep things dry, and ensure your feet stay warm.
These socks are thicker than other Sealskinz sock products since they have a thermal rating of 4.

The socks are a bit higher than ankle length for a little extra protection. Good for times when the trails are filled with deep puddles.
An MVT middle layer (also called the Moisture Vapor Transfer layer) helps to ensure wearers do not get their activities cut short by water infiltration. The waterproof design keeps wearers comfortable and keeps water completely out. Unfortunately, some users did point out that the waterproofing lacks durability.
The interior is made of fleece, so these are a bit thicker than other options made with Merino wool. They are meant to protect users from the cold in wet weather.
- True to size
- Protect from the cold
- Comfortable fleece interior
- Stretchy outer material
- Waterproofing layer is not durable
Here’s How We Put Our List Together
We evaluated our top ten picks for Sealskinz socks according to four criteria. We looked at hundreds of user reviews to determine whether folks found the socks comfortable and sufficiently waterproof. We also looked at the different sock thicknesses and heights during our research and evaluation.
Considering comfort is kind of a no-brainer. Everyone wants their socks to be comfortable. We looked at what type of padding each Sealskinz sock had and whether reviewers found the socks comfortable to wear. We also looked at comments from users on the sizing and fit of the socks and whether the waterproofing hindered breathability. We also took care to note whether users were comfortable in the socks even for long periods of time.
We looked at each pair of socks and noted the length to determine the kind of protection each sock offered. A higher cut means a more protective design. Some Sealskinz socks also have a special Hydrostop cuff to produce a unique seal against water even at the top of the sock.
All Sealskinz socks are waterproof (except for the liner that we included on our list). There’s no denying that Sealskinz constructs the socks with attention to detail to ensure water is repelled and kept out of the sock. But what does that mean for comfort? How is the waterproofing achieved?
Some models feature a Hydrostop cuff to keep out water completely. Unfortunately, this type of feature is not suitable for activities of longer duration because the seal is tight fitting and may cause chafing. While most reviewers were incredibly happy with the waterproofing of all the Sealskinz socks we looked at, we also wanted to look at how well the sock was able to breathe even with this waterproof technology.
A waterproof sock is great for keeping moisture out but what about handling sweaty feet? Sealskinz socks are impressive in that they keep water out but do provide some degree of ventilation to ensure wearers don’t stay sweaty and wet inside the sock. How is this achieved? Through the use of a Merino Wool layer, which we’ll talk a little bit more about later.
Sealskinz evaluates the thermal rating of their socks on a scale of 1 to 4. Even the thinnest Sealskinz socks, however, still have a layer of padding and are not as thin as a traditional super thin running sock. The thicker the sock, the warmer they are. The thickness helps with impact protection but may also work as an obstacle against proper fitting inside a shoe, which is why we paid close attention to each sock’s thickness and warmth rating.
The majority of Sealskinz sock products utilize a Merino Wool lining to handle moisture. While the water blocking middle layer keeps water out, the Merino liner ensures that any moisture produced by the feet does not cause discomfort. Merino Wool is a useful moisture management tool, but its biggest strength is its ability to also regulate temperature. It’s hard to believe, but the Merino layer in Sealskinz socks actually helps to keep feet warm, even when the socks are very wet.
What activity do you plan to participate in while wearing your new Sealskinz waterproof socks? If you’ll be out and about in warm weather but need some waterproof socks, look for options that feature a lower cut and are in the lower range of the thermal rating scale. For colder weather, choose thicker socks with a higher cut. Whatever the activity, make sure that if you choose a thicker sock that you can still wear your favorite footwear.
Most Sealskinz socks are fairly pricey but they’re on the higher end of the price scale for good reason. The highly technical socks provide 100% waterproofing and are also windproof. For the price you pay, you’ll be getting maximum protection from the elements, something budget socks just cannot provide.
Q. Is Merino Wool a natural or synthetic fabric?
Merino Wool is a natural fiber that comes from a specific breed of sheep. This type of wool is a lot gentler on the skin, isn’t as itchy as traditional wool, and has special properties that make it a great choice for making gear for the active individual.
Q. I’m looking for a pair of socks for running, should I go with a waterproof Sealskinz sock?
Although a waterproof sock may seem like the best idea since sliced bread, a waterproof sock for running may not be the best option. Unless you’re running half your runs through water-filled areas, you probably don’t need something as heavy duty as a Sealskinz waterproof sock.
For running, look for a sock that dries quickly and can move sweat away from your feet. A Sealskinz sock will do this to some extent, but most of the socks offered by the brand are on the thicker side and may not fit properly inside your running shoe, especially if you’re used to wearing thinner socks on the run.
Q. Are Sealskinz socks only good for cold winter activities?
Not at all. If you’re outdoors in warmer weather but getting your feet very wet, a pair of waterproof socks may be a good choice. Prolonged exposure to water or soaking wet socks is not good for your feet. So even if it’s not super freezing out, a pair of waterproof socks may be a good idea.
Q. Sealskinz socks are expensive, are they worth it?
This brand of sock provides not only waterproofing but windproofing as well. You could spend even more money on a pair of waterproof boots but what happens if you want to participate in different activities that require different types of footwear? A pair of waterproof socks from Sealskinz allows you to wear whatever you want on your feet. In the grand scheme of things, you might actually save money!
Q. Couldn’t I just cover my feet with plastic bags? Why use a pair of Sealskinz?
Sure, you could do that but it would quickly become uncomfortable and might even produce unpleasant blisters. Not to mention, you’d probably need to adjust those plastic bags frequently. Plastic bags are also easily ripped and torn. They’re not a permanent solution. Sealskinz socks are durable, waterproof, and also provide protection from the wind. They don’t just provide protection, though, they also help to ensure your feet stay warm.
Q. What length of Sealskinz sock should I consider?
That depends on the type of water depth you’ll be encountering on the move. For maximum protection, a knee-high length is your best bet.
