Shoes are very important for a pain free existence. If shoes do not fit properly then you can have pain in your knees, back, ankles or hips. Comfortable shoes are more important than some people think.
It is a good idea when you purchase shoes to try the shoes on and make sure they fit properly. It's very nice to have a good looking shoe but the fit is much more important. Buy shoes that fit your foot properly and you will feel better.
Shoes should be breathable to your feet. Shoes made of natural materials are better for you than plastic or man-made materials are. Leather or cotton lets your feet breathe while nylon or other synthetic are more air tight. Pick out natural materials whenever possible.
When you try on a shoe, it should bend at the same spot your foot bends. When you walk it is important for your comfort that your shoes bend along with your foot. A shoe that does not bend with the foot can create blisters and sore spots.
A shoe should not be able to twist from side to side. The shoe should fit snuggly on your foot yet it should not be too tight. A shoe that is too tight can be very uncomfortable and cause foot pain.
