100%other Made in the USA or Imported Merino Wool: Merino wool is soft, cool in the summer and warm in winter. We source our 100% U.S. grown merino wool exclusively from sheep raised by American farmers on American farms. Light Cushion: Cushion that is light in weight along the base of the foot only. This all-season construction is highly versatile. 3/4 Crew: A slightly shortened crew that fits just below the calf but above a hiking boot. Seamless Toe Closure: Advanced knitting techniques create a totally flat connection in the toe box, reducing bulk and eliminating blister-generating friction. Durability Assured: Reinforced construction and low-stress seam placement reduce wear and tear, increasing the life of the sock.
