Year and a half ago I was in the throes of plantars fasciitis and my wife showed me how she keeps hers in check. Stretching the calf muscles. Well, that was not enough for me and I added massaging the bottom of my feet with a hard rubber ball, which at first hurt like hell, but now is a welcomed comfort. The final step was wearing zero-drop shoes. Altra is my choice and have used 4 different models of their shoes with great success.
I tried Hoka, but the Altra shoes are better for my condition. FWIW, my job requires me to walk anywhere from 3 to 7 miles a day and I get in and out of 12-30 cars and trucks in that time, thus there is a lot of tension on the lower legs and feet.
