Two of the most common and convenient calf stretches are bending the front of the foot against a wall, and bending the ankle/heel downwards over a nice sharp edge.
We are told by the shoe makers that our shoes should last for a mere 400 or 600 kms, but ironically - how much does this stretching prematurely damage our delicate - and not inexpensive running shoes?
Does this explain why my shoes are feeling a bit shagged after 300 kms? How do you know when your shoes have had it?
