Walking 30 minutes a day, five days a week calls for careful selection of your most important equipment — your shoes. The right ones will not only make your daily walks more comfortable, but will also help prevent strains, sprains, blisters, and calluses. Follow these tips for finding the perfect pair:

• Look for essential qualities. Walking shoes should flex at the forefront, have a low supportive heel, and be lightweight and breathable.

• Buy the correct size. They should fit about one size to a size-and-a-half larger than your dress shoes.

• When in doubt, ask an expert. Running/walking store staff can assess a variety of factors to determine the most appropriate shoes for you.

• Know when to replace them. If you’re walking an average of 30 minutes a day, replace your shoes every 6 months.

The best shoe provides support, flexibility, and cushioning for your foot and stride.
