Dec. 11, 2025—If you want to treat your feet right—and you should—don't overlook the importance of a good pair of socks. Just like your choice of shoes, the socks you slip on can affect the health and comfort of your feet. Here are a few ways the right socks can make a difference.

Blister prevention

A painful blister can sideline you from your favorite activities. It might even boost your risk of other sports injuries, like stress fractures or tendinitis, the American Academy of Podiatric Sports Medicine reports.

Much of what we know about socks and blister prevention comes from military studies. Researchers found that socks made from synthetic fibers that draw away moisture from the skin may help prevent blisters. (Moisture increases friction by making your skin stick to the socks.) Other good features for preventing blisters include socks with padding in blister-prone areas of the foot, like the toes or the heel, and socks made with double layers.

A proper fit is also important to prevent blisters—the socks should not be too tight or loose.

Also, avoid socks with prominent inside seams that might hurt your feet.

Tired feet and leg vein problems

Compression socks (or knee-high stockings) may provide some relief for people with circulation issues, such as varicose or spider veins. They also help people whose legs get tired and swollen because they work a job that keeps them on their feet a lot. In addition, many people wear compression socks on long flights to reduce swelling—and possibly the risk of deep-vein blood clots.

You can buy compression socks over the counter, unless you need some that provide higher compression. Your doctor can help you choose the right compression socks for your needs.

Winter warmth

Warm socks are an essential part of dressing smart during outdoor activities in cold weather. Not only do they help you stay comfortable, but they might reduce your risk of frostbite.

Experts recommend wearing two pairs of socks. The pair near your skin should have moisture-wicking fabric, and the outer sock should be made of wool or a wool blend, according to the American Academy of Dermatology.

Sweaty feet

If your feet sweat a lot, it could be a condition called hyperhidrosis. Excessive sweating is more common among men and younger adults, notes the American Podiatric Medical Association (APMA). And it can lead to foot odor and foot infections. If you're worried about sweaty feet, tell your doctor. The APMA recommends moisture-wicking socks (natural or acrylic fiber blends). Avoid 100% cotton; it absorbs moisture instead of removing it.
