HealthSmart: Let the shoe fit the activity

Many of my patients think there's no difference between running shoes and walking shoes. But the biomechanics involved are different.

Joggers should get shoes that emphasize overall shock absorption. Walkers need shoes that not only give them heel cushioning but also help shift weight smoothly from heel to toe. Soccer, tennis, basketball, aerobics — each presents unique challenges to the foot. The American Orthopaedic Foot & Ankle Society offers these tips:

• When buying shoes, always have your feet measured (don't just go by size).

• If you're an exerciser, get fitted after a session, when your feet will be a little larger.

• When trying on shoes, wear socks that will be worn with the shoes.

• Since many folks have feet of different sizes, fit your shoe to the larger foot.

• Make sure there is at least one thumb's breadth of room between the longest toe and the tip of the shoe.

• Those who have foot or toe problems, such as bunions or hammer toes, should select shoes with wider toe boxes.

• If the shoes are not comfortable, don't buy them.
