Bad news flip flop enthusiasts: this wafer thin footwear has a list of offenses that shouldn’t be taken lightly. Simple rule: if your shoe of choice doesn’t provide any kid of support for you feet, toss it out! The longer you wear bad shoes, the worse the consequences! Aching heels, flat feet, broken toes and fungal infections, back and knee problems, to mention a few. Wow. Maybe flip flops should solely be used at the beach.
