Love these socks!

These Micro Light Runner socks fit perfectly and are super comfortable. They are my go to pair! I love the way the top of the sock lands just above the ankle. Great look!

Great Fit

Love the comfort of the micro light runner quarter. I walk 60 miles a week in comfort with no blisters or bruising. The merino wool is the reason I purchase these sock. Definitely a plus above socks!

Met my expectations and more!

The quality is visible immediately. Snug comfortable fit- don’t slip down in my athletic shoes. Wash well. I like the low height so a bit of the colored rim shows for fashion! I will be buying these again!

Best Socks Ever!

I've had FITS hiking socks for a few years and it never occurred to me to use them for any other occasion. I've tried many brands for running, gym and everyday usage. They would wear out after a few months and my feet would always be sweaty and cold at the same time. These micro light runners are now my every day socks. Feet are the perfect temp, the socks dry fast and they are so comfortable and durable. They are thin enough to fit in all of my shoes. Love the quarter height!



The Perfect Fit Starts With the Right Size.

Your sock size shouldn’t be a guessing game. Our socks range from small to double XL, but the best way to know the perfect fit for you is to match your shoe size to the chart on the left. That way, you’ll know the size you select will give you the fit and feel you expect.

Between sizes? Go with your gut, but rest assured that your socks will still fit great. If you receive your order and find yourself wishing you’d gone up or down a size, just let us know. We’ll happily send you replacements for your preferred size.

Concerned about laundry mix-ups? All FITS® socks are coordinated by color and size, based on the colors you see on the size chart. So, you won’t have to worry about mixing up your sizes with the other FITS® wearers in your home. (But stray socks mysteriously going missing in the dryer? Unfortunately, we can’t help with that.)

Questions? Let’s talk.
