Good hiking socks are expensive but worth it. Look for breathable fabrics that will keep your feet dry as well as cushioning key areas to keep your feet comfy during long days on the trail. Smartwool’s PhD Pro Hike Crew Socks ($27.95, smartwool.com) comes in different designs and combine merino wool, nylon and elastane to create a warm, breathable sock. They’re also designed to guard against rubbing that could cause blisters. Royal Robbins’ Venture Crew Sock ($22, royalrobbins.com) is unisex, comes in various colors (I like Arctic blue) and adds cushioning to support the arch and back of the ankle. There are no seams on the toes, another way to avoid friction on your boots.
