Injinji Sizing Guide

From concept to production, Injinji socks are designed with your feet in mind! Our unisex, women’s-specific and men’s-specific sizes provide a snug fit around every foot to give you a better performance in any shoe. Your Injinji toesock size is based on your shoe size and can be easily found using the chart below. Unless otherwise noted, all Injinji socks are unisex. If you’re new to the world of toesocks, we recommend wearing your Injinji socks a few different times to allow your feet to adjust to our unique fit.

Still have questions? Check out common sizing questions below the sizing charts.

Do Injinji socks run true to size?
Yes they do! Our size guide measurements are based on your shoe size. For instance, if you wear a men’s 11 shoe, we recommend going with a Large – which fits sizes 11-13 on our unisex sizing guide.

What is the difference between Unisex, Men’s and Women’s socks?
Great question! Our unisex socks are our most common fit and the best size for medium to wide feet. Our women’s-specific fit is shorter in the toes and narrower in the arch of the foot, making our women’s socks a great fit for people with narrow feet! Our men’s sizing chart only applies to our Men’s Runner and Hiker series and is best for medium to wide feet.

What are the best socks to get if I’m in-between sizes?
If you’re on the edge, we suggest going with the larger size! Getting a larger size allows your toes to move comfortably all day and is the best sock for in-between size feet.

Is there a special way to put toesocks on?
Nope! Just begin putting your socks on like normal, and make sure each toe is set properly into its individual sleeve before pulling the sock up to your heel. For our compression socks only, we recommend rolling the sock inside out, setting your toes and heel in place, and then rolling the socks up around your calves.

Do Injinji socks shrink after washing them?
Not if they are cared for properly - Injinji socks are made to give you the best performance fit through their entire lifetime! For maximum time enjoying your socks, we recommend washing them on delicate in cold water and hanging them to dry. Putting the socks in the dryer increases the chance of the socks pilling.

Can I return my socks if they don’t fit?
Injinji can return or exchange unworn socks in the original packaging up to 60 days from the date of purchase. For questions about our one year limited warranty, please visit our Warranty page or email us at cs@injinji.com.
