Fit & Design: Merino wool is soft, itch-free, naturally odor- and bacteria-resistant, cool in the summer and warm in winter High-density cushion targeting critical performance areas throughout the sock A slightly shortened crew that fits just below the calf but above a hiking boot Advanced knitting techniques create a totally flat connection in the toe box, reducing bulk and eliminating blister-generating friction Reinforced construction and low-stress seam placement reduce wear and tear, increasing the life of the sock
