The Best Fitting Sock on the Planet

Our most popular hiking sock style, the Light Hiker, is cushioned under foot to take the pounding of an all-day hike while managing all the moisture you can throw at it.

  • Our patented Full Contact Fit® hugs the contours of your foot and stays put so there are no loose socks to rub you the wrong way.
  • Crew height rises just below the calf
  • Extra cushioning in the heel, toe and the arch



Finding your perfect fit is an important part of what makes FITS® so unique. Don’t worry- if you’re torn between two FITS® sizes, your socks will still fit. Remember, we want you to have YOUR perfect fit. If you’re not completely satisfied, let us know - we’ll replace that pair for your preferred size. Give it a shot - you won’t be disappointed!

Please use your shoe size to find the perfect fit for you! Also note that your shoe size will match the corresponding color in the toe seam.  For example, if you're a men's size 6-8 or a women's size 7.5-9.5, your toe seam will be blue.
