These Smartwool socks are great for hiking and everyday wear. Put them on like you would any regular socks. Make sure they fit snugly but not too tight. When it comes to washing, use a gentle cycle with cold water to keep the Merino wool in good shape. Avoid using fabric softeners as they can reduce the sock's performance. After washing, lay them flat to dry to prevent shrinkage. Keep them away from sharp objects to avoid snags. If you have any old Smartwool socks, don't throw them away. Send them back to Smartwool to support their recycling program.
