The Macpac Unisex Hi Merino Socks is just what you need when hiking up a storm. This technical hiking sock is designed to have all the temperature regulation, breathability and odour resistance that Merino wool is known for. With full cushioning and a smooth toe seam for warmth and comfort, plus an elasticated foot arch for a snug fit (which also helps to prevent the sock riding down in your boots), you'll be supported every step of your journey.
