stretch that foot
Something like this was recommended by chiropractor. She said that it's better to have heel on floor than hanging off edge of step, as I had been doing. I actually bought two, and leave them in plain sight so I am reminded every time I go into living room or bedroom (which is many times, of course) to pause a moment for a healing (and enjoyable) stretch. I'm pretty sure that combined with rolling sole on lacrosse ball, this device is helping keep my feet tennis-ready.
