I am concerned because my feet tend to swell a lot during the day. I am 49, overweight with a desk job, but I try to get up and move at least once an hour. I drink an average of 80 ounces of water a day. When I workout, either on the elliptical or doing zumba, and wear tennis shoes, my feet do not swell and look normal. When I wear sandals, they tend to swell, but not every day. I have been trying to eat healthier to manage my weight and I use very little salt. I am just concerned this may be a symptom of some other problem. I do not have pain in my feet or legs and I am a non-smoker.
