It’s important to choose warm socks for skiing, but you don’t want to sacrifice fit for fluff. A snug-fitting sock can mean the difference between a day of shredding and a day of nursing blisters. Thick socks can be tempting but too much bulk can actually lead to colder feet and cut off circulation. Instead, opt for a slim moisture-wicking sock (anything Merino is perfect) that will keep your feet dry. If that doesn’t do the job, consider investing in some heated socks for long-lasting toasty toes.
