The Balega Enduro Quarter Sock has held the top spot in Runner’s World’s Best Running Socks guide for two years, and readers like it almost as much as the popular Darn Tough Run Ultra Lightweight Cushion Quarter Sock. That kind of staying power deserves a closer look. For me, the case starts with durability: I’ve owned a pair since joining Runner’s World as a gear editor, and after plenty of miles and some use away from running, they’re still intact apart from a little pilling near the toes. But longevity alone doesn’t explain the following.
A Soft Sock That Endures
Balega Enduro Quarter Socks — $15 at Amazon; $18 at Balega
Pros: Secure heel and ankle fit; light arch compression; plush but lightweight cushioning; breathable over the arch.
Cons: Loose threads along the inner stitching; no sex-specific fits.
Soft cushioning for long miles
Here’s the thing: several Runner’s World editors find the Enduro comfortable enough to wear around the house like a slipper. Its medium footbed cushioning adds a soft layer between your foot and the shoe’s existing insert and midsole. That plush feel also makes it a sensible pick for long runs and trail runs, where extra protection can help when rough ground takes a toll on your feet.
Balega also sews a compressive V-Tech band into the sock, designed to follow the arch and provide support. The fit and cushioning make a persuasive everyday case; the data here doesn’t tell us how much the band contributes on its own. Still, if you want a quarter sock that feels soft without giving up a secure hold, the Enduro has earned its popularity.
Why the Quarter Cuff Works
Sock height gets debated at run clubs for good reason: the wrong cuff can slide down or leave your Achilles rubbing against a shoe collar. The Balega Enduro’s quarter length lands in a practical middle ground. That balance is more significant than it looks once you’re several miles into a run.

The sock uses Balega’s Drynamix yarn, a proprietary polyester weave designed to move moisture away from the foot and help prevent blisters. Ventilation panels add airflow, while seamless construction limits rubbing and bunching. Those details matter more over long runs than they do on a quick trip around the block.
Fit Depends on the Shoe
Unisex sizing once made me wary, especially for running shoes. But some brands now make shoes—and socks—that can fit people of different sexes well. And if a particular shoe doesn’t work for your foot, the wide range of options means you can keep looking. That’s one reason [finding the right running shoes](https://www.runnersworld.com/gear/a19663621/best-running-shoes/) is a matter of fit, not just sizing labels. The reviewer wears a size 5 in everyday shoes and a 6.5 in running shoes because she has [wide feet](https://www.runnersworld.com/gear/g39135738/best-wide-toebox-running-shoes/). In the Enduro, a small fits comfortably without slipping. There’s a tradeoff, though: the sock’s thicker fabric can bunch around the toes in some shoes. It’s a poor match for a narrow, minimal [speedwork trainer](https://www.runnersworld.com/gear/g44064559/best-carbon-plate-shoes/) or track flat, where every bit of extra material can feel crowded.
