I buy the cheapest black, rubber-soled shoes I can find at Payless. I usually spend $15-20 per pair and buy two pairs at a time. Each pair lasts about 5-6 months. I have never had a problem with back/leg/foot pain *knocks on wood*. I just can't justify spending $100 (or more) on a pair of kitchen clogs that will last about as long as $100 worth of cheap Payless shoes.
