Discuss the variations in foot shape and the type of shoes that are required for each foot shape

The basic food shapes are wide and narrow. If you have flat or wide feet, it can be repaired through insoles replacing the inside of the shoe. These insoles can help the foot maintain an arch while wearing shoes like boots or sneakers. People with narrow feet don't necessarily need any repairs, but some shoes wont feel as comfortable or won't support the arch. A good example of a shoe made for people with high arches is Altra's Tortin 2.0

The type of shoes one purchases should depend on the person's foot shape. There are three variations: normal, flat-footed, and high arches. Those with high arches tend to roll their foot outward while running. Shoes with more cushioning and flexibility are required in this case. People who are flat-footed roll their foot inward; this movement demands a shoe that provides more stability. People who have normal-shaped feet can choose just about any shoe because most shoes are designed to fit this type.
