Rather than avoiding your problem, I suggest you solve it. For starters, go to Walmart, or Target, or Fred Meyers and pick up a hand held vibrational massager. Nothing fancy, $25-50 should cover it.
Now, to use this, stand on a step with only the ball of your foot making contact. Let your heel hang down as far as possible. This should put a good streth on your gastrocs. Then, set the vibrational massager to its highest setting and apply it to the calf. Move it slowly around the surface of the calf while it's in the stretch.
Do this in sets of one minute per calf a few times per day. You should be back in working order in no time.
