Why Runners Are Reaching for Compression Socks
Compression socks apply graduated pressure to your lower leg, tighter at the ankle and gradually easing up toward the calf. That gentle squeeze is designed to help support circulation, which is why so many runners wear them both mid-run and during recovery.
The recovery case is strong. Many runners find that wearing compression socks after a tough effort may help reduce that heavy, achy feeling in their legs the next day, meaning you may feel ready to lace up again sooner. During a run, compression socks are designed to help keep your ankles feeling stable and your calves supported, which can be especially noticeable on longer distances.
During a Run vs. After: What's the Difference?
Both approaches have their fans. Some runners wear compression socks for calf support during the effort itself; others pull them on immediately post-run and let them work while they rest. A lot of people do both. Try it and see what your legs prefer.
What to Look for in a Running Compression Sock
There are a few key things that separate a great running compression sock from one that just looks the part.
Compression Level (mmHg): What the Numbers Mean
The pressure in compression socks is measured in millimeters of mercury, or mmHg. For running, most experts recommend 20 to 30 mmHg, firm enough that you can feel the support, but comfortable enough to wear for hours. Go too light and you may not notice much benefit; go too tight and you'll be distracted by your socks instead of your pace.
OUTWAY's knee-high compression socks sit at 20 to 25 mmHg, hitting the sweet spot of that range for everyday training runs, long efforts, and post-run recovery alike.
Sock Height: Knee-High vs. Ankle
Knee-high compression socks cover the most muscle tissue and are the go-to for distance runners and anyone dealing with calf tightness or fatigue. Ankle compression options feel less restrictive and work well for shorter runs or warmer weather. You can explore OUTWAY's full range across both heights at the links below.
Fabric, Breathability, and Cushioning
Look for moisture-wicking fabrics that move sweat away from your skin, ventilated zones to help prevent overheating, and a seamless toe to help reduce blisters over long miles. If you run in variable weather, merino wool blends are worth a look. They naturally regulate temperature, resist odor, and hold up well wash after wash.

Both work and it comes down to personal preference. Wearing them during runs may help with calf support and reduce ankle fatigue. Wearing them after may help muscles recover faster. A lot of runners do both.
Compression socks aren't a cure for shin splints, but they may help support the lower leg and reduce discomfort during a flare-up. If shin splints are a recurring issue, it's worth talking to a physio or sports medicine professional about the root cause.
For most runners seeking circulatory support, knee-high is the stronger choice. More coverage means more potential benefit for the calf and lower leg. Ankle styles are a good lightweight option for shorter efforts or hotter days.
For knee-high styles, measure the circumference of your calf at its widest point. OUTWAY sizes primarily by calf circumference rather than shoe size for over-the-calf compression socks. When in doubt, check the size chart before ordering.
