I used to have a real problem with foot cramps and cramping in legs and then it stopped for several years or longer. I've recently started walking 1/2 hr a day and wear really good supportive walking shoes. The foot cramps have started again and it seems usually they are on days when I had to skip the walk usually because of weather. I used to be able to take a flexaril when I had them and the cramps would pretty quickly subside. Is there a foot brace I could purchase that would possibly help me to stop the foot cramps
