Absolutely! Shoes act as casts that weaken the feet and prohibit flexibility. What's more, they act like incubators, providing a perfect breeding ground for all of those nasty foot ailments like fungus, ingrown toenails, corns and bunions. It's one thing for your feet to hurt because you've been standing or walking all day, but it's another for them to hurt because of your shoes -- yet that's what millions of people chose to do every day. Bottom line: Shoes definitely do more harm than good to your feet.
