Blisters on Your Feet when Running?
Having blisters during an endurance (or any) event just sucks! Now I am not saying that you can completely prevent them but having the correct footwear is critical. My number one rule is avoid cotton socks!
Look for wool socks or synthetic blend socks.
Why?
They draw away the moisture. Cotton socks absorb moisture and that contributes to sliding. Sliding = friction and friction = blisters. When you are doing any athletic activity it is my recommendation that you completely avoid these socks as there is a higher risk for these blisters to occur.
