The Women’s Classic Hike Full Cushion Crew Socks are the perfect choice for any hiker looking for extra padding – with full cushioning throughout, enhancing both warmth and protection inside and out. Meanwhile, Smartwool’s Virtually Seamless™ Toe technology smooths out the sock’s toe seams for the ultimate in-shoe fit and comfort. The sock is also updated with a new construction that combines responsibly sourced, ZQ-certified Merino wool and recycled nylon – making the socks more sustainable. Care Instructions Machine wash on a warm and gentle cycle. Do not bleach. Do not iron. Do not dry clean. About Smartwool's Merino Wool ZQ Merino is used to ensure the sheep that produce the wool are treated humanely, the wool growers are treated fairly, and the farms work to minimise their impact on the environment. Smartwool also helps protect the areas and activities we love by partnering with advocacy organisations that align with its values.
