A blister is a small, painful pocket of fluid that builds in the upper layers of the skin.
You can avoid blisters by wearing good-fitting, broken-in boots and socks that provide cushion and wick moisture from the skin. If certain parts of a foot are prone to blistering, pretreat the area by placing mole skin or an adhesive bandage over it. Long and sharp toenails can lead to rubbing against a shoe and boot and thus blisters on the toes. Always remove tiny stones and twig pieces from a shoe. As soon as your foot or that of your kids’ feels any pain, check the foot for a “hot spot,” an area of inflammation that is on the verge of becoming a blister.
Always treat a hot spot as soon as you feel it by placing an adhesive bandage over the affected area. While you generally shouldn’t pop a blister, do so if hiking. Then clean the blister with antiseptic and dry it to help relieve pressure and to prevent the blister from spreading, which will occur if your keep walking. Place a piece of mole skin over it, secured by an adhesive bandage, so it does not continue to rub against the boot.
As a side note, place a little foot or baby powder in your boot before hiking. While this won’t prevent blisters, it’ll help reduce moisture on the foot, making the walk more comfortable.
