Choosing the perfect running socks for summer can be difficult. You need to factor in weight, price, size, fabrics, materials, thickness, length, comfort, cushioning, and moisture-wicking technology. That's a lot to think about. But ultimately, all it really comes down to is the type of running you'll be doing. Think about whether you'll be using your socks for sprint training, short runs, long runs, or ultra training. To make your decision even easier, we’ve rounded up the best running socks for summer, so your feet will be protected and you’ll have enough energy to run your personal best.
Picking the right pair of running socks doesn't have to be about choosing the most expensive pair. It’s about choosing the ones that are lightweight, fit well, designed with technical materials, and equipped with strong sweat-wicking properties. Don’t forget - your feet sweat too!
It seems like most people focus on picking the right running shoes, while running socks often get neglected.

Therefore, it’s best to look for high-performance or technical running socks that create the right fit and environment for your feet. Not only are they comfortable, but good running socks can also add padding, cushioning, and support. Now, let's review the 10 best running socks.

Want to run like an elite runner? The Compressport Pro Racing Socks are the ultimate package. They provide complete support for your feet, excellent comfort, and perfect moisture management.
There’s also a 360° slight compression band around the arch support that stops the socks from turning or sliding down your shoes. The biggest advantage of the Pro Racing socks is that they stimulate venous return and provide more tonicity to your stride.
For ventilation, the socks feature striped vented zones around the feet. The socks also dry very quickly thanks to the fast-drying fibres. There’s also added reinforcement around the big toe to protect from the impact of the ground.

BEST FOR LONG RUNS
Inspired by Japanese Zen culture and its focus on balance, Salomon Nso Long Run Socks have been designed by ultra-trail champion François D'haene. The socks are made with mineral oxide technology which provides more energy, improves muscle tone, and helps with recovery.
The Salomon Nso socks limit the movement of your foot inside the shoe. This allows you to run longer, especially with challenging terrain. The cushioning in the socks absorbs shocks and reduces heating when running for long distances on difficult terrain.
Salomon Nso Long Run Socks customer Matt S. says, “Most comfortable and supportive socks I’ve worn running!”
Another happy owner, Matthew R. said, “Great socks for hiking. Awesome socks! They fit well, perfect for long hikes, my feet never blister with these socks. Love them so much I am ordering more.”

Similar to the Salomon Nso Long Run Socks, these socks differ in that they're mid-length rather than long. The Mid Run Socks feature a mix of merino and polypropylene that manages sweat, allows your feet to breathe, and reduces bacteria.

Wigwam Surpass Ultra-Lightweight Low Socks owner Deborah S. said, “Consistent quality, durability and comfort. These socks are lightweight and comfortable. Once I find a product I really like such as these, I am a loyal customer. I use these socks for every day use and find them durable enough for doing farm chores. They keep my feet clean and they are actually so lightweight that I hardly know I have them on. This version of low cut stays nicely in place on my big feet, with ventilation to the skin for cooling off. Highly recommend.”
Another happy customer Stephen Y. said, “Great lightweight socks for running. For hot and humid days, I wear these Wigwam, made in the USA socks. Zero chaffing and super light. Backed by an excellent warranty, I only wear Wigwams and Darn Tough socks. They last a long time!”

BEST FOR TRAILS
Some may argue that the Salomon Nso Long and Mid Run Socks are better. At the end of the day, they’re very similar, but the Smartwool PhD Outdoor Ultra Light Crew Socks are better for trails. The difference is that they’re much lighter.
The Outdoor Ultra Light Crew Socks are marketed as elite, minimalist running socks. The latter is spot on as they’re made for people who want to run like an elite trail competitor.
The Smartwool socks are made out of Indestructa Wool technology (merino wool with nylon) for extra stretch. They feature new Shred Shield technology for reduced wear from toes.
PhD Outdoor Ultra Light Crew customer Marcus Y. said, “Comfortable, thin socks. Good for running, not a lot of cushion, but feels supportive and not restricting. Sizing is good. Definitely breathable!”
Another happy owner Brent C. said, “Comfy. I’m a fan of these socks, I own two pairs of this version. They are thin and I wear them while walking, hiking, and running. They keep your feet warm in colder weather and not too hot in warmer weather. Great product.”

Breathable
4 Degree elite fit system
Durable Indestructa Wool technology

Some reviewers have found them to be a “bit tight”

The ASICS Performance 2 No Show Socks provide moisture management to keep feet dry and comfortable when running.
Customer Matthew G. said, “Great all-rounders. Great little socks, thin on top but with good padding on the heel and toes. I wear them for 12-hour shifts in the hospital and then on my 5k jog home, no blisters or noticeable wear and tear.”
Another happy owner Brad C. said, “I wear a lot of Asics products from shoes to jackets to shorts to shirts to socks. They never let me down. These socks are high quality and a great deal with the “six-pack.” I’ll buy again.”

BUYING GUIDE: WHAT TO LOOK FOR IN RUNNING SOCKS
When shopping for the best summer running socks, you need to think about the type of running you'll be doing. Are you doing sprint or interval training at the park? Are you running to and from work? Are you training for a half marathon? Do you like to run trails on the weekend?
Once you know what kind of running you’ll be doing, you should pay attention to the following factors.
TYPES
No-Show Socks
These low-cut socks soak up sweat, which then prevents bacteria and bad odour. Low-cut socks are a great choice during summer, as the shorter socks keep runners' legs cool. Look for non-slip silicone grips on the heels to keep them in place. Since no-show socks are so small, it’s important that they retain their shape and size after wearing or washing.
Ankle socks
Ankle socks offer a lightweight design and height that is often used for athletic and casual wear. Look for ankle socks that are lightweight, and with arch support, blister tab, and toe seams features.
Crew Length
Crew length socks are normally worn during colder weather. They add protection for off-trail runs. Crew length socks are prevalent in compression socks. Look for a compressive material that reduces swelling in the ankles and calves and assists with blood flow.
Breathable Material
Socks made out of synthetic materials like acrylic, polyester, and nylon are the best, as they’re breathable and sweat-wicking.
Comfort
Comfort is one of the most important factors when choosing a pair of running socks for summer. It makes the difference between a good run and a bad run that turns into a walk. Focus on the padding when choosing a pair and look at customer reviews.
Cushioning
Look for recent running socks that provide additional cushioning and padding around high-impact areas like the toes, balls of the feet, and heels.
Value
Focus for running socks that come as a six-pack like the ASICS Performance 2 No Show Socks - Unisex or the Salomon Cross 2-Pack Socks - Unisex. You’ll get good value for money.
FAQs
Do good running socks make a difference?
Yes, good running socks can be the difference between a good run and a bad run. Choosing the wrong pair will lead to frustration or tears due to blisters, bunching, and slipping.
Are ankle socks better for running?
Although some ankle socks can slide down into the shoe, compression at the ankles provides support when running, making them a good choice for your run.
Should running socks be thick or thin?
Thin running socks are better during the summer, as they’re lighter and tend to have a better feel for the trail or road. However, thin socks can also lead to blisters.
When should I replace running socks?
Toes poking through your running socks is a dead giveaway for needing to replace them. On average, you should be replacing your running socks every two to three months, depending on how often you use them.
Conclusion
There you have it—the best running socks for summer 2021. Focus on choosing a pair of running socks that meets your personal goals.
