I've heard good things about improving your vert, but I doubt you'll add any size to your calves. The muscle fibers that control your vert are fast twitch. To stimulate hypertrophy in your calves I would focus on deep squats and calf raises.

yea and im also trying to improve my ankle flexibility. i haven't tried it yet but it feels like it would defiantly increase your vertical and explosiveness with the way it stretches out your Achilles and calves.

Yup, used these for 2 summers at speed camps for football. Calf endurance went through the roof. I became way more agile after the first summer using them.

They don't really build mass, just aid in making you faster and more explosive.
