Have you been training your calves?

Cardio exercises might not be enough. Isolation exercises, on the other hand, will do the trick.

The leg press, for example, can help you build strength and endurance in your calves.

Adjust the seat position to where you can comfortably extend your legs without moving the machine.

Place both feet on the machine, adjust the weight stack to a challenging weight, and push the platform out.

Then walk your feet down so that the balls of your feet are against the platform and your heels have no contact.

With soft knees, contract your calves to raise up, pause, and then lower to full extension without locking your knees.

Try 20 to 25 quick repetitions.
