Micro light finds amazing middle ground

The micro light socks find a great middle ground in the FITS lineup. Great for warm running/hiking but with more cushion than their lightest.

Lifetime runner

I am 68 years old and have averaged running 5 miles a day for 50 years. I am very picky about socks. The micro light runner is the most comfortable sock I have found. I wear them running and as casual wear.

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.
