Picture of Blisters
Wearing shoes that do not fit properly or wearing shoes without socks can cause blisters, which can become infected. When treating blisters, it's important not to "pop" them. The skin covering the blister helps protect it from infection. Use an antibacterial cream and clean, soft bandages to help protect the skin and prevent infection.
