Tips for Finding a Blister-Proof Sandal
Avoid wobbly shoes. Examine a shoe's quality by looking at how it sits on a table. A well-built one will be balanced and look stable when standing on its own.
Find stack heels that have a broad heel tap (base), which allows for better shock absorption. You will also be steadier on your feet.
Stay away from backless shoes, such as thongs and slides, because they cause pain in the balls of the feet, says Suzanne Levine. Instead, look for a sandal with straps that hit just below the ankle (not encircling it). These will help stabilize the foot and hold it securely.
Wear only sandals that have leather or suede-lined straps to prevent chafing.
Make sure the toe-box area is wide enough for the broadest part of your foot.
Look for platform shoes that give the illusion of a higher heel without the feel of it.
Examine the insides of straps for seams and other construction details that might dig into feet.
