Bad shoes can cause pain and discomfort, as well as problems with your feet and legs. In some cases, they can even cause arthritis. Bad shoes also affect the alignment of your joints, so you may be more likely to experience problems in these areas. They can also lead to other health issues, such as infections and ulcers. If you’re a woman, bad shoes can also cause embarrassing wardrobe malfunctions, such as being unable to zip up your dress or having a protruding shoe heel.
