Best Merino wool socks for feet that sweat

Gone were the days when if you had sweaty feet, wool socks were a no-no. Traditional wool socks tend to be bulky and they don’t regulate temperature well so they are only suitable for extremely cold weather. Plus, they can cause odor, sweat, and itchiness to the skin.

Merino wool socks, on the other hand, have cooling, odor-resistant, and moisture-wicking properties, which makes them an ideal option for men and women with sweaty feet. Merino wool is also a super soft fabric similar to silk and cashmere.

Whether you need a good quality wool sock for hiking, running, working on your feet, traveling, or casual wear, there are many available merino wool options out there. You just need to find the right style, height, and thickness, plus some additional features if necessary.

Need a little help to decide? Here are the best merino wool socks for sweaty feet. But, first:

What Is Merino Wool?

Merino wool is a special type of wool that comes from Merino sheep. These sheep breeds have been bred in Spain since the 12th century and were brought to Australia in the 18th century. Today, the leading countries in providing the world with merino wool are New Zealand and Australia.

Merino wool is a natural luxurious wool made from super-fine fibers that keep your feet comfortable and dry in most weather conditions. How about finding more about why this specialty wool is great for sweating feet as well as various other issues.

Merino Wool Socks Benefits

  • It keeps your feet dry: Unlike some synthetic fibers, Merino wool doesn’t wick sweat when it´s a liquid already, but the moisture is transported away from the skin while it is still a vapor. Plus, it gets quickly absorbed by the pores of the fabric so you don’t end up with sweaty cold feet in cold weather or after your workout. Merino wool’s moisture-wicking properties make it ideal for people wearing work boots as well as walkers, runners, and hikers.
  • Retains your body temperature stable: The natural wavy fibers of the wool trap air, which keeps you warm in cold temperatures, but at the same time, they are breathable. Wool can absorb 30% of its weight in water before it starts feeling wet. As the sweat evaporates, it creates a cooling mechanism that helps regulate body temperature. This is one of the reasons why merino is suitable both for winter and summer wear.
  • Resists odor: Since merino wool absorbs moisture well, there is no wet environment to promote the growth of odor-causing bacteria or toenail fungus which thrives in those humid environments. It also contains lanolin, a natural substance that is said to have anti-odor, anti-microbial, and other properties beneficial for the skin. This means you can use merino wool socks for long hours of wear such as working on your feet, traveling, and even for backpacking without having to worry about clammy feet and unpleasant smell.
  • It’s Soft and durable: The diameter of a Merino wool fiber is smaller than an average sheep wool fiber. That’s what makes the wool of the merino breed really soft and super-fine, which is great in terms of preventing skin irritation and blisters. It is also inherently super strong and its natural crimps add elasticity and durability. Plus, it holds its shape and size well even after multiple washes.
  • Provides UPF protection: Merino wool is a great material for the summer not only for the reasons we have explained above but because it also features UPF protection. Its ability to block out ultraviolet rays is higher than most synthetic fabrics and cotton. As the sun normally causes more damage if you’re trekking in the mountains, merino clothing is a good option for mountaineers and outdoor enthusiasts.
  • It Biodegrades: The eco-friendly apparel trend is growing fast. According to New Zealand researchers, merino wool biodegrades after 9 months in the soil. On the other hand, synthetic materials such as polyester are not biodegradable at all.
  • It’s fire-resistant: Due to its natural flame and fire-resistant properties, merino doesn´t melt, so it’s a good material for firefighters and campfire enthusiasts.

How To Choose The Best Merino Wool Socks

For sweat-free feet and the rest of the benefits Merino wool is well known for, look for the following features:

Odor Resistance & Sweat Absorption

Merino wool is naturally odor-resistant and moisture-absorbent but there has to be enough of it in your socks blend to be effective. Generally, the higher the amount of Merino, the better. Most quality merino wool socks contain more than 60% Merino wool.

An adequate amount is a good sign for providing you with all the benefits of this specialty wool including moisture control, softness, and comfort.

Other Materials

Many people wonder if there are 100% Merino wool socks. My answer is that I have yet to find such a product. The reason is that including synthetic materials in the blend improves the performance of these socks.

For example, synthetic materials make the socks more stretchable and elastic. They also help them stay up and make them more durable and fast-drying. An adequate percentage of Merino wool combined with at least 20% or more of synthetic fibers is the best sock blend for sweaty feet or other foot needs.


There are several criteria to choose the right height socks for your needs. Often, people choose the height of their socks according to the height of their shoes.

For example, if you are buying socks for your work boots or hiker boots, it’s good to choose the right height so you can prevent skin abrasion from the boot tops and achieve longer performance. Taller socks also provide a good fit around your calves and reduce the pressure of working boots. If your boots are high- or mid-cut, you will need at least quarter or crew socks.

Another factor to consider is the weather. If the weather is warm, you don’t need to buy a very tall sock. Finally, choosing the right height socks is also a matter of style preference.


Padding on the areas of the foot that it’s more needed such as the heel and the ball is an excellent feature to go for if you are looking for a good pair of running Merino socks. Cushioning provides relief to the feet especially during those long trips over tough terrain and it can prevent skin irritation and blisters.

To achieve a better fit so your shoe doesn’t feel too tight, choose less padding. Or choose extra cushioning if you think that you need it.

Arch Support

Some brands offer socks with a tighter weave in the area of the arch to promote support. This can be helpful for people with regular arches but even more useful for people with foot issues such as flat feet, high arches, or plantar fasciitis. It can also help to prevent foot arch blisters.

However, keep in mind that a sock with arch reinforcement is not going to work as a replacement for a supportive slipper or any other type of footwear with arch support.


Choose the right size so your sock is neither too long nor too short. When you try on the sock, pay attention to how it feels in the heel and the toe. Also, tight weave socks stretch less over time and provide a better fit. They also hold up better after repeated washings. Plus, if the weave is too loose, it can cause problems with pilling and bunching.

Extra padded socks can make your shoes feel too tight, so you should try them on with shoes before buying or make sure that the weave is not too thick if you are buying online.

The Bottom Line

Merino wool fibers are perfect for transporting sweat away from the skin and canceling out odors. They are comfortable, soft, and great for every season and activity. If you are wondering whether merino wool socks are worth it, remember: once you try out one of the best Merino wool socks for sweaty feet in the review above, you will never want to go back to your cotton socks again.
