Good shoes are worth every penny if you need to spend a majority of your day on your feet and on the move. I cannot say enough about the importance of a rocker bottom soled shoe. Many walking shoes and hiking boots have a rocker-bottom built into the front or forefoot of the shoe. And for most people that is all you need, a good pair of walking shoes in white or dark.
For those who need a safety shoe or boot, look for the ones with the curved soles. The curvature of the sole reduces the amount of stress on the joints and ligaments in the foot because this curvature rolls the foot along from the moment the heel strikes the ground to the moment the toes lift off.
By reducing the amount of weight your feet have to endure all day long, you might experience less pain at the end of the day. And if you are carrying too much weight on your frame, you should definitely be wearing good, supportive shoes.Nothing is more distracting then really sore feet on the job. You might not be able to focus on your work if all your mind can think about is getting off your feet, taking your shoes off and putting your feet up.
