5. Don purpose-made running socks
Avoid socks made from cotton, which absorbs moisture and can cause blisters. Socks made from synthetic materials are a better option, as they're durable and sweat-wicking.
If your marathon goes off-road, consider longer socks to protect your calves. But if you're running on pavement alone, pick a comfortable length. For the best marathon running outfit, choose cushioned socks that bring extra support.
