Buying the lowest price shoe may cause you to pay a higher price later in food or ther problems. A good pair of exercises-walking shoes will cost between $60 and $90. Some national discount stores advertise athletic looking shoes for less than $30, but they have cheap composition material in the midsoles that mashes down and often aggravated pronation.
As a word of causion, all athletic type shoes look pretty good when brand-new. The difference between a $25 pari and a $65 pair is in the materials, controuction, and support systems. Remember, you only get what you pay for. Don't buy cheap athletic-type shoes for exercise-walking!.
