In reply to Removed UserGRUMPY MONKEY:
Are we talking indoors or outside? Slabs or something steeper? What happens if you go for a run? Do you take any other form of exercise? Have you tried, for example, doing heel raises with your toes on a book, in bare feet? What happens if you climb the stairs with your heels well away from the steps?
It seems a bit premature to be talking about climbing shoes.
Screaming calves on long slab routes is par for the course.
