Flip-flops are okay for crossing the beach, but you should never make them your everyday summer shoes.
You could sprain your ankle
Those rubber flip-flops you got for a cheap price are fine for the beach. But you won’t want to wear them every day, all day. They have absolutely no arch support, meaning your feet will begin to turn toward the middle of your body instead of staying straight. When that occurs, you’re may possibly sprain your ankle
Your foot could get inflamed
Even if you’re really careful and don’t twist your foot, that absence of arch support can kill your feet. Without the right support, your plantar, the band of tissue in the arch of your foot, will begin to pull. That pulling aggravates the tissue, making your arch painful and red from a condition called plantar fasciitis. When you try to step down on your foot, you have agonizing pain in the arch.
Foot problems could go bone-deep
With too many attacks of plantar fasciitis, your body will begin making new bone to try to heal the pulling. With more bone than the body needs, a buildup known as a heel spur could come on the bottom or back of your heel.
Objects could poke through to your foot
It doesn’t take long for a pair of cheap flip-flops to get worn down. Once the heel and toe start to go, it’s easy for glass, dangerous objects, and nails on the ground to poke through. But the flip-flops themselves are a bigger issue because a tetanus shot won’t protect against them. Part of the shoe can get embedded in their foot and create a foreign body.
You’ll twist your toes in—and they’ll stay there
Flip-flops are, okay, floppy, so you possibly need to curl your toes down to keep them from coming off while you walk. But wear them enough and they may not straighten out once your shoes are off. The toes can bend up and stay in that fixed position that looks like a little hammer.
