My calf structure, shape and insertion points are almost identical to my fathers. They look good when tensed but lack overall size. You can grow them but it takes a large amount of calf raises. If you have a gym membership get in and do a lot of calf raises, 3-4x a week minimum. Blast them, as people have said. 3-4x per week for a few months of blasting them will help.
It is largely genetic though. I saw a guy at the weekend with the most monstrous calves I'd ever seen in my life, but overtook him going uphill. He's probably pissed at all us skinny calved guys racing past him.
