The 7 Best Crew-Length Running Socks For All Weather
Crew-length socks are having a moment, but we’ve always loved them for running. Here are our top tested picks for this year.
Socks are often the unsung heroes of footwear, but an ill-fitting or poorly made pair can be the difference between a lovely outing and a miserable limp back to the car. And despite my millennial affinity for low-cut and no-show socks, crew socks are having a moment not just due to the endless cycle of trending apparel, but because taller socks offer protection from overgrown trails, prevent debris from cascading into your running shoes, and add insulation during cold runs. (And fine, maybe they don't slide down into your shoe as often. You may have a point, Gen Z.)
The best crew socks aren’t just the calf-covering style we picture when we think of crew socks. Crew socks actually come in several heights, though there is no dedicated naming convention. For instance, Darn Tough calls their 7.5-inch socks “micro crew” while Swiftwick calls their 7-inch socks “crew.” For the sake of this guide, I considered full crew, micro crew, and quarter-crew socks, and also listed cuff height in the specs.

The Expert: I am a Montana-based gear tester who gets outside all year round for my mental health. This means running, biking, and hiking in a variety of conditions, and taking my footwear into consideration for everything from trail running to HIIT workouts to winter slogs on icy sidewalks. I’ve been testing outdoor apparel and gear for 10 years, and my reviews have appeared in Runner’s World, Bicycling, Popular Mechanics, the Strategist, and Outside. I am currently an editor at Switchback Travel, where I test apparel and gear in a range of activities.
What to Consider When Shopping for Crew Running Socks
Socks aren’t as straightforward as they appear, and there are a few key considerations to remember when choosing your next pair. Keeping the material, the height, and the weight in mind will help ensure you stay blister free, keep your temperature regulated, and are able to forget about wearing them. To me, forgetting that I’m wearing socks is the sign of a good sock.
Look for a Combo of Natural and Synthetic Material
Years ago, cotton and synthetic might have been the primary material in running socks, but these days a merino / synthetic blend is far more popular. Merino wicks moisture, which helps prevent blisters, and the synthetic material (usually nylon or polyester) helps the socks retain structure and support. I have some fully synthetic socks—often lighter and faster drying than merino blends—but synthetic socks have less odor resistance than merino, and that smell will eventually just bake into the sock. I suggest shopping for crew socks made with 35- to 65-percent merino or other natural fiber, and the remainder a durable synthetic with 3- to 5-percent elastane for support and shape retention.
Which Crew Height Do You Want?
Full crew: Full crew socks are the tallest crew socks on the market and are more common in hiking varieties. These extend 6- to 9 inches above the heel portion, and can cover a good percentage of your calf. I wear full crew socks in cold weather for added insulation and to help protect from snow, and they also pair well with gaiters. (And for your non-run life, they're a Doc Marten must-have.)
Micro-Crew: These are what I think of when I think of crew socks. They extend 5- to 7 inches from the heel to top of the cuff, and don’t reach as far up the leg as full crew models. This is my favorite middle ground, and I find them to be versatile enough to offer protection without feeling too hot. They also come in a range of cushioning options, from ultralight to full cushion.
Quarter-Crew: Also called mini-crew, quarter-crew running socks rise over the ankle, but not much further. These have a cuff height of around 3- to 4-inches, and offer more protection than a no-show sock without the actual crew look. These wouldn’t be my first choice for trail running, but I love them as my warm-weather socks for road runs. They prevent some debris from falling into my shoe, but don’t feel excessive during the summer.

What Cushioning (Thickness) Do You Need?
Ultralight and lightweight socks are great for summer and shorter runs, and won’t have as much reinforcement around the footbed, toes, and heel. I also find them to breathe better. Medium cushion socks are my choice for trail running and longer outings. They tend to feel warmer thanks to the added underfoot material, but I appreciate that they help reduce fatigue over long distances. Keep in mind that thickness and cushioning doesn’t refer to the strands of fiber themselves, but the density of the knit and reinforcement for high-impact areas.
I would be remiss if I didn't mention style. While the colors and patterns have little to do with the functionality, they can get you just a little bit more excited to lace up and get out there. Running socks used to be boring, but now, not only can you have a comfy run, but also pretty fancy feet, and I think that's great. Read on to check out my favorite crew-length running socks.
