Antiperspirant reduces the sweating that creates friction, and friction leads to blisters. Wash and dry your feet every day for five to six days before a major walk, run or hike. Cover your entire foot, in between toes, tops of toes, backs of heels and bottoms of feet. Whether you use stick, spray or roll-on, just make sure you didn’t miss any spot. Just one missed spot could lead to sweating and blisters. By reducing sweating, antiperspirant also helps existing foot blisters to heal faster. CLICK HERE to find out more health tips.
