Frequently Asked Questions

What are the advantages of using Injinji toesocks?

By redesigning the basic structure and shape of a traditional sock, toesocks help to enhance the function and freedom of the foot while inside any shoe. The five-toe interface provides total foot utilization helping to properly align and splay the toes allowing the entire foot to be engaged in any athletic activity. With each toe wrapped in sweat-wicking material, skin-on-skin friction is eliminated helping to protect against blisters and hotspots. Whatever athletic endeavor, there is a toesock for it, as Injinji strives to make the journey of life more comfortable.

When will my order ship? How long will it take to receive my socks?

All orders are processed typically on the following business day. If you select economy ground, you should expect to receive your socks in 4-8 business days. For premium ground or free shipping, you should expect to receive your socks in 2-5 business days depending on location and weather. Orders with 2 Day shipping placed before 8am PST will be shipped same day, however all expedited shipping orders placed after 8am PST will be shipped on the following business day. If you have questions about shipping methods please contact our customer service team!

Doesn’t it feel funny wearing toesocks?

No way! Toesocks might look uncomfortable but we have a legion of toesock converts who say they are pretty darn comfortable! It’s true a toesock might feel a little different from a traditional sock at first, but a smile is sure to spread across your face once you walk around and test them out. You’ll quickly learn why people nickname their feet “happy feet” when rocking a pair.

What shoes can I wear my Injinji’s in?

Injinji socks can be worn and enjoyed with any shoe! Seriously - Go ahead and pair your Injinji socks with your favorite pair of running shoes, tennis shoes, hiking boots, office flats or dress shoes. Your feet will thank you.

My toes are a funny shape. Will they fit me?

Toes in all shapes and sizes will fit into our wonderful toesocks. The first pair takes a minute or two to get on but after that, it’s smooth sailing putting our socks on! The toesock sockets will become molded to your big, small or crooked toes allowing them to wiggle freely with glee.

How should I care for my toesocks?

You can start with hugging and telling them how much you love them every day. Just kidding! Okay, sort of but we won’t judge if you do. Machine wash your Injinji’s using the gentle/delicate cycle. Line drying your socks is the best method to protect the quality of the sock fiber. Do not bleach, iron or dry clean your Injinji socks. We also highly recommend that you trim your toenails to prevent premature wear.

I’m on the edge of a size – do I size up or down?

Oh decisions, decisions! We suggest going a size up if you teeter on the edge of a size. Example, if you are a Men’s 10.5 but sometimes wear a size 11, we recommend choosing a size 11 sock or a Large.

What is the difference between CoolMax and NuWool?

CoolMax and NuWool are both incredible fibers to choose from when picking the right Injinji sock. CoolMax is a polyester blend that uses state of the art technology to keep your feet cool and comfortable by wicking away moisture even in the most extreme of conditions. NuWool fibers are made from the finest Australian Merino Wool. Our Merino wool is compact spun to provide superior durability and to prevent itching. NuWool also provides maximum temperature control, odor resistance and wicks away moisture naturally. No matter what fiber you choose, you will reap in the benefits of wearing these moisture wicking power houses that keep feet super cool and dry!

What is the difference between the Lightweight, Original Weight and Midweight socks?

Injinji has not one, not two, but three sock weights available to meet your needs! First is the Lightweight sock which is Injinji’s thinnest sock. Lightweight socks provide ultra-thin cushioning for extra breathability and a light feel in any shoe. Next up is the Original Weight sock. This sock has the thickness of a traditional sock and provides a moderate cushion ideal for a wide range of activities. Injinji’s thickest sock is the Midweight. Designed for maximum protection, the Midweight sock features a padded heel and metatarsal for extra durability and protection.

Are they hard to get on?

It will take a few extra seconds to properly fit your Injinji toesock onto your foot. Right out of the package, the toe compartments are flat and have yet to form to your particular toe shape. Once you have worn and washed your socks once or twice you will find that the sock material has a memory and your toes will slide into the pockets with relative ease. Make sure you “set” your toes in their individual sleeves before you pull the sock over your heel.

Can I find your socks in stores? How can I find one near me?

Small local running shops to outdoor retailers like REI carry a range of our products. Check out our Dealer Locator to see what stores carry Injinji socks. We recommend contacting the store before you head out to see what socks and sizes they carry.

How can I get free shipping?

Who doesn’t love free shipping? We provide free shipping on all orders over $60 to addresses within the U.S. Orders to Canada are not eligible for free shipping due to customs and duties. Time to get shopping!

I live outside of the U.S. Do you ship internationally?
