Our Men's socks are designed to be stretchy and accommodate a lot of different feet! The complexity of a design will decrease the stretchiness, but generally, most men's socks will fit a men's US shoe size 7-13 and women's shoe size 8.5-14.5.

Our STRETCH-IT™ Wide Calf Knee Highs are made on a special machine that gives them incredible stretch without distorting the designs. They'll generally fit a men's US shoe size 7-13 and women's shoe size 8.5-14.5, and up to a 21" calf.

However, due to the stretchiness, they fit a huge range of calf and foot sizes and look great. A survey of our loyal STRETCH-IT™ fans showed us that 2 out of 3 fans wearing these socks self-reported having a 15-inch calf and wearing a US women's size 9 shoe. All folks we surveyed own and love multiple pairs of our STRETCH-IT™ socks! They'll also go higher up on the leg, so they're perfect if you're taller and looking for a comfortable awesome knee high sock.

Our kid's socks are soft, stretchy and ready for little feet! The Youth socks fit children's shoe size 8-13 or ages 3-6 and the Junior socks fit children's shoe size 1-5 or ages 7-10. Please keep in mind the complexity of a design will decrease the stretchiness, but overall our socks are pretty stretchy!

As we introduce more unisex socks to our line, we want to be sure you can still find your perfect fit. Check out the chart below to see what size you will be.
