6. Banish blisters
Blisters strike more often in hot weather. They’re caused by rubbing, especially between the toes if you’re wearing flip-flops with "thongs". Lorraine Jones, a podiatrist from The Society of Chiropodists & Podiatrists, says the key to preventing summer blisters is to keep your feet dry, wear shoes or sandals that fit well and aren’t too loose, and give your feet ample rest so they don’t get hot and sweaty. If you do get a blister, don’t put a plaster over it. Leave it to dry out on its own.
