Customer Reviews

As a nurse who is on her feet all day, finding compression socks that are both supportive and comfortable has been a challenge. After trying several brands, Therafirm socks are hands-down my favorites! The 20-30 mmHg compression level gives my legs and feet the right amount of support without feeling too tight. I love how the socks keep my legs from getting fatigued and achy even after 12 hour hospital shifts. The fabric wicks away moisture and my feet never get overly sweaty. I can even wear my favorite shoes thanks to the smooth toe seams. Therafirmsocks come in so many great colors and patterns too. The quality shows in how long they last - over a year with frequent washing! For nurses or anyone on their feet a lot, I highly recommend these socks for all-day comfort.

As an avid runner, I'm always looking for ways to improve performance and speed up muscle recovery. Therafirm compression socks have become my go-to for both training and recovery. After long runs, wearing them for a few hours really helps flush out lactic acid and reduce swelling. I also love wearing them during races and training runs to increase blood circulation in my calves and ankles. I've found Therafirm to provide the right amount of compression without being too restrictive. Plus the fabric is super lightweight and breathable, even when my feet heat up. The socks hold up amazingly even through intense running and repeat washes. For any fellow runners looking for that extra edge, I can't recommend Therafirm enough!

As a busy mom of three kids, it's hard to find time to sit down and rest my feet during the day. I developed some swelling and varicose veins that were becoming painful. My doctor recommended medical compression socks to help with circulation and immediately pointed me to Therafirm. I have been so pleased with these socks! The 20 mmHg compression provides noticeable relief from swelling without feeling uncomfortable. They are easy to get on and stay in place. I was worried about sizing but Therafirm's size chart was right on target. Best of all, the socks don't look medical at all. I've received so many compliments on the cute patterns! The quality shows in how well they've held up to frequent all-day wear. I highly recommend these socks for other moms in need of relief!

As someone who loves traveling the world but suffers from poor circulation in my legs, finding good compression socks has always been a must. After trying dozens of different brands over the years, I can confidently say Therafirm socks are the highest quality and most comfortable brand I've worn. I like that they offer various compression levels so I can choose 15-20mmHg for shorter flights and 30mmHg for longer international trips. The snug yet stretchy fit hugs my legs perfectly whether sitting for hours on a plane or walking around museums all day. They do a great job preventing swelling and that heavy leg feeling. The soft fabrics keep my legs cool and dry even with extended wear. Plus Therafirm has cute styles I can wear out to dinner without an "old man medical sock" look. After relying on these socks for years of pain-free travels, I wouldn't dream of using any other brand!

As an expecting mother, finding maternity clothes that fit comfortably has been a challenge. My legs especially swelled up during the third trimester. My OBGYN recommended Therafirm maternity compression socks to help improve circulation in my legs and ankles. I'm so glad she did! These socks provide the perfect amount of light compression to reduce swelling without being too tight on my belly. They stay in place without rolling or sagging. The fabric stretches nicely to accommodate my growing belly and legs. Therafirm's sizing chart helped me order the right size to fit my pre-pregnancy shoes. The soft material feels great on my skin and doesn't itch or cause overheating. I've been wearing my Therafirm socks daily and will definitely keep using them postpartum. I highly recommend them to any expecting moms for comfort and healthy circulation!
