The 9 Best Running Socks

The Feetures – Elite Max Cushion socks were the all-around favorites among our testers. A great choice for both warm and cool weather, they kept our feet snug but not sweaty, thanks to their “iWick” fiber blend (74% polyester, 21% nylon and 5% spandex). Although the fabric itself isn’t the softest of those we tested, the socks were breathable and received high comfort ratings from our testers.

The Feetures socks fit the foot like a glove, with excellent compression under the arch. They’re also seamless, preventing any rubbing against the toes and potential blisters. The “Max” socks we tested (they also come in Light and Ultra Light versions, for those looking for a thinner sock) have extra cushioning in the toe and heel area, which strikes an excellent balance with the thinner, breathable body of the sock. Feetures offers a lifetime guarantee on its socks that allows you to replace your pair once they start to wear out, no questions asked.

It was a close race between the Balega – Blister Resist and Feetures socks, but the Feetures’ all-weather breathability ultimately won them the gold. Our testers loved the Balegas, but found them to be slightly on the warmer side and better for cool weather — though still very breathable. The Blister Resist socks are made of 34% nylon, 2% elastane and 64% “DryMo,” a blend of the brand’s moisture-wicking Drynamix polyester and natural mohair, which is anti-microbial and has been shown to help prevent blisters.

The Balegas mold perfectly to the feet, with medium compression in the arch area. Save for the arch, the entire bottom of the sock and the toe area have more padding than the Feetures sock, which may be why they felt warmer. Like the Feetures pair, these also have a seamless toe. Balega offers a one-year warranty on their socks.

The Rockay – Accelerate Anti-Blister socks offer the most arch compression of any pair we tried. This strong compression helps the sock stay in place on the foot, preventing chafing and making them ideal for blister prevention. They are also one of the thinnest pairs we tested, and are well-ventilated throughout to prevent moisture build-up.

Like the Balega – Blister Resist socks, the Rockays feature seamless toes and padded soles except for the arch (though the Rockay padding is on the thinner side for extra breathability). Impressively, the Rockay socks include recycled materials: 66% nylon, 30% organic merino wool and 4% elastane. This moisture-resistant blend kept our feet dry as we ran, and received one of the highest ratings for breathability (the highest rating went to the Swiftwick socks). Rockay offers a lifetime guarantee on their socks.

The Swiftwick – Aspire Zero socks are ideal for summer runs, or for runners with particularly sweaty feet. The thinnest of the socks we tested, they feel ultra-lightweight and allow for excellent airflow around the foot. These socks offer medium compression in the arch area — less than some of the other socks we tested, but the Swiftwicks are so thin and close-fitting that they stay in place on their own without the help of intense compression.

Made of 55% nylon, 40% olefin and 5% spandex, the Swiftwicks’ moisture-wicking, lightweight profile doesn’t offer much cushioning, so they may not be the best choice for trail running. As we noted before, ultra-thin socks like these are best worn with a well-fitted shoe, to prevent the foot from sliding around inside the shoe.

Thick and on the warmer side, the Darn Tough – No Show Light socks are ideal for running in cooler temperatures. They received high comfort ratings from our testers, with a good amount of cushioning running the entire length of the sock’s sole. The Darn Tough socks fit snugly, with a thinner top for breathability and medium compression in the arch area to help keep them in place on the foot.

Sweat-wicking and odor-resistant, the Darn Toughs are made of 51% merino wool, 46% nylon and 3% lycra. Our testers found them to be a little less aerated than some of the other socks in our lineup, but that’s the trade-off of wearing a warmer, more insulated sock. Darn Tough offers a lifetime guarantee on their socks.

The Balega – Hidden Comfort socks are especially cozy, with soft, uninterrupted sole cushioning from heel to toe that received top marks for comfort from our testers. Though the tops of these socks are thinner to allow for ventilation, we should note that their padded arch made them warmer and less breathable than the others. Made of 84% moisture-wicking Drynamix polyester, 14% nylon and 2% elastane, the Balega socks stayed dry for the most part, though we did notice moisture building up inside our shoes on longer runs.

Because the Hidden Comfort socks provide little to no compression, double-check your size to ensure a snug fit and minimize sliding within the sock. Balega socks come with a one-year warranty.

We recommend the Wrightsock – Coolmesh ii for runners with particularly petite-sized feet because their smallest size fits women’s shoe size 5. Many running socks we’ve tested typically run larger, and this often leaves too much room for movement during runs and causes excess friction. Our tester, prone to sweaty feet, liked the breathable mesh panel design that prevented blisters.

We like that the lightweight fabric also keeps our feet dry and cool during runs but still provides ample cushion for the feet, so it’s comfortable. The only issue we had while testing these socks was that the double-layered socks often came out of the laundry floppy, and we had to fix the placement so there weren’t any uncomfortable folds or seams after putting them on. However, this issue was not a deal breaker and was quick to fix. Read more…

Since these socks are so lightweight, we recommend them for travel because they don’t take up too much room or weight, and the polyester nylon material dries quickly after washing. We recommend the Wrightsock – Coolmesh ii socks if you have small feet and want a breathable, lightweight sock for traveling.

If you have trouble with blisters between your toes, the Injinji – Run No Show socks are worth a try. Designed like toe socks, with each toe individually encased in fabric, the Injinjis are made to reduce inter-toe rubbing and wick moisture away from the skin between the toes.

Our testers tried out both the Lightweight (63% nylon, 32% CoolMax polyester, 5% lycra) and Original (68% nylon, 29% CoolMax, 3% lycra) Injinji Run socks, and both were quite breathable with plenty of airflow. Besides their unique toe design, both pairs have the most minimalist design of all the socks in our lineup, with very little compression. The Lightweight pair has virtually no padding, and the Originals is only slightly more padded in the toe and heel area.
The Injinjis take longer to put on, and the sensation of individually wrapped toes takes some getting used to. However, if you’re prone to between-the-toe blisters, these socks may be worth the extra trouble. Injini offers a one-year limited warranty on their socks.

The Smartwool – PhD Ultra Light is a basic running sock that we found to be good but not great. This simple, straightforward sock has a thin, lightweight body that offers light compression and minimal padding located only at the very tip of the toe area.

Made of 48% nylon, 48% merino wool and 4% elastane, the Smartwool socks allow for good airflow throughout the foot. Though the Smartwool socks are lightweight and breathable, our testers agreed that this sock doesn’t seem to excel in any one area beyond that. They’re not snug enough in the arch to provide much compression, and their cushioning leaves much to be desired. Compared to the other stand-out performers in our line-up, the Smartwool sock is just okay. However, with Smartwool’s two-year satisfaction guarantee, you’ll have time to try them out and reach your own verdict.
