I work on my feet and always have. No other flats are as reliable as dexflex. They always fit perfectly, never pinch my toes, and wear in perfectly in one or two days. I wear these flats until the soles literally have holes in them and they remain comfy up until the very end. Ive even worn them hiking and they conform to your foot and grip the ground so well I had a better time of it than my husband in boots.
