Yes, waterproof socks exist and yes, they are really waterproof. Here’s when to wear them, when to skip them, and some of the best waterproof socks to wear hiking or anytime feet need to stay dry and warm.
What makes waterproof socks waterproof? It is similar to wearing a plastic bags between two socks, and much less sweaty. Waterproof socks are made of three layers with a waterproof membrane sandwiched between knit socks. The outer and inner socks have to be thick enough to protect the membrane from damage so these socks will be thicker than athletic socks but can be comparable to heavy hiking socks.
It is easy to test who waterproof these socks are – put one under the tap and fill it with water like a balloon. However, water can get in where the cuffs meet the leg. Waterproof socks need to be higher than water when wading through or covered by waterproof gaiters or pants to work in the pouring rain.
Waterproof socks do more than keep feet dry. They also block out mud, sand, dust, and wind and help toes stay toasty. These socks are also useful for many other outdoor activities including biking, hunting, kayaking, surfing, paddleboarding, and anything else that gets the feet wet or uncomfortable
All that being said, waterproof socks are more of a preference than must-have hiking gear. Here’s how to decide if and when you need them.
When To Wear Waterproof Socks
Waterproof socks easily upgrade non-waterproof footwear or increase the coverage of waterproof footwear. They are also helpful in damp and wet conditions.
Try waterproof socks if:
- You prefer to hike in non-waterproof trail runners, sandals, or athletic shoes
- Waterproof shoes aren’t in the budget at the moment
- Very wet conditions or terrain
Waterproof socks are so effective that many hikers wear them with their favorite lightweight shoes and sandals – year round.
When Not To Wear Waterproof Socks
The membrane that keeps water out also keeps some sweat in, which can be hot and damp. They may not be the choice for all day wear, hot conditions, or people with sweaty feet.
That being said, the combination of mesh shoes and waterproof socks can be more breathable than a Gore-Tex shoe. Try out different sock and footwear combinations to find the best one for you. Switching up the insole can also make a world of difference in shoe comfort.
If hot feet or perspiration is an issue, a sock liner or a generous does of foot powder can help.
There are also products dedicated to minimizing foot moisture. Deodorants for feet reduce perspiration and odors. Try Carpe Antiperspirant Foot Lotion or SweatBlock Lotion. Blister prevention powders also work by minimizing moisture. Check out 2Toms BlisterShield, waterproof powder that repels moisture instead of absorbing it. These products can be used on their own or together.
In summary, these socks are excellent hiking gear but only wear them when they are required.
Waterproof Socks vs Gaiters
There is an overlap between the benefits of waterproof socks and gaiters. Gaiters keep water and other elements out of waterproof shoes but they do not make shoes waterproof. Gaiters could be worn with waterproof socks to keep moisture out of the cuffs.
Other than that, it all comes down to preference. Many hikers prefer the lightweight, cushioned soles of trail runners. When waterproof, they can be worn with gaiters but waterproof socks can make any shoe waterproof.
Waterproof Sock Layers
The challenge for all waterproofing is the balance between allowing air out without letting water in. Most waterproof socks use Coolmax in the liner sock for its moisture wicking, anti-bacterial properties. Coolmax absorbs sweat from skin quickly to keep feet dry, odor free, and reduces blister.
Some socks use natural fibers like wool or bamboo. Of course, the breathability of all these fabrics is reduced by the waterproof membrane. There will also some percentage of Spandex, Elastane, and/or Lycra for stretch.
Each sock company has their own waterproof membrane.
For the outer sock, nylon and/or polyester are used for their water-resistance. There will also be some added stretch.

Do Waterproof Socks Work?
Waterproof socks absolutely work when worn and washed correctly. If water comes in from above the sock, feet will get wet. This can be a deep stream or wet pants.
The balance between breathability, stretch, and water-resistance mean that the inner membrane is delicate. Follow the washing and drying instructions to extend the life of socks.
How Do You Wash Waterproof Socks
While some brands can be put in the washing machine, hand washing socks can extend their lifespan.
Even machine-washable waterproof socks need to be air-dried, which can take up to 24 hours. To shorten drying time, I like to put the socks between two towels and press out excess water. Repeat the process on the inside and outside layers. When the outside layer of the sock is dry, flip it inside out to let the inside dry.
