Feet come in all sizes, yet although shoes differ in type and style, how many of us wear the best shoes for our feet?

The 26 bones in each foot do not fully set until we are around 18 years old, and the shoes we wear as children are vital to our future foot health. However, we can still do enormous damage to our adult feet by wearing the wrong shoes.

Choosing the best shoes

Badly fitting footwear can be very damaging to feet. In fact, many adults' foot problems occur because they wear poorly fitting shoes throughout their life. To help prevent damage to your feet, try applying the following rules when you buy shoes. Similar rules will help for buying children's shoes or shoes for specialist conditions such as diabetes.

WHAT SHOULD YOU LOOK FOR?

HEEL: This takes a large proportion of a person's weight. Unfortunately, the height of the heel is often determined by fashion, not by the needs of our feet. Ideally, the heel should have a broad base and the heel height should be no greater than 4cm.

HEEL COUNTER: The portion of the shoe that grasps the heel of the foot at the sides and back, preventing the heel from sliding up and down while walking. Most importantly, it stabilises or helps maintain the position of the heel when the shoe contacts the ground. As the heel counter softens or breaks down and loses its shape, the shoe becomes less supportive. Not all shoes have a heel counter. The heel counter should complement the shape of the heel of the foot.

SOLE: The entire bottom of the shoe. It should be flat, except for a gentle slope upwards under the toes.

UPPER: The material that forms the main part of the shoe covering the top of the foot. Ideally, it is composed of a natural material, e.g. leather.

LINING: Found inside the shoe and should be smooth and without seams.

FASTENINGS: This holds the foot in the shoe. Shoes should have laces, straps with buckles, or velcro to keep them in place. 'Slip on' shoes are kept in place either because they are too small for the foot, or by curling the toes.
