The easiest way to tell which sock style you have is by the color of the letter on the bottom of your sock.

We offer three different compression levels to fit your activities and lifestyle: firm (20-25 mmHg), moderate (15-20 mmHg), and relaxed (10-15 mmHg). Compression socks support your muscles, especially around the arch of your foot, and prevent bunching and slipping for a perfect fit every time. Whether you prefer firm structure or relaxed support, there's a compression option for you.

Our socks come with the recommended instructions of "Machine Wash Cold. Tumble Dry Low. No Bleach or Iron."

Swiftwick sizing is based on your corresponding shoe size. Please refer to the size chart below.

	MEN	WOMEN	EURO
S	3-6½	4-7½	34-38
M	7-9½	8-10½	39-42
L	10-11½	11-13	43-45
XL	12-15	13½-16½	46-49

The initial variation in size largely depends on the time that has passed since they were knit. Newly knit socks will tend to be a bit longer than socks that were knit a few months ago. This is due to some residual moisture content in the fibers and a natural setting process that occurs with the elastic over time.

The fitted size of each sock, in other words, the number of courses or stitches along the length of the sock, should be exactly the same. It is also not uncommon for socks to appear different after a wash since they are pressed before being packaged. After a couple of wears and washes, you should notice no difference between the pairs and this will not affect functionality in any way.

All of our socks can be worn on either foot. Our socks are marked with the size on the bottom. If your sock has a colorful "L" on the bottom, that indicates a size Large, not left.
