Q: How do I prevent blisters?
— Carter, San Diego, Calif.

A: Blisters are pockets of fluid that form under your skin. They’re your body’s natural way of protecting itself, but they’re uncomfortable and sometimes painful. Friction, pressure and moisture often cause blisters, so before you hit the trail:

• Make sure your boots fit well and don’t rub against your foot or ankle when you walk.
• Keep your feet dry and cushioned.
• Wear socks that wick away moisture and help reduce friction, such as those made with merino wool. Point6 merino wool performance socks ($22-$33, point6.com) are a nice option, providing breathability, moisture management and cushioning in key areas to keep your feet comfortable on the trail.
• A cheaper alternative is wearing synthetic liners with your regular socks.
• If you’re kayaking or canoeing, wear gloves and keep a loose grip on your paddle to prevent blisters on your hands.

You know a blister is forming when you feel a “hot spot” on your foot. Place a piece of moleskin or duct tape on the tender place to add extra cushioning. You can also try Wūru blister wool ($11.95, wuruwool.com), which soaks up moisture.
