They need to have a low center of gravity.
thats funny you said that. isnt rob dyrdek also short? well not ALL skateboarders are short. i hav a friend that skateboards, hes 13 and like 5 somethin maybe 5'5 but also my other friends brother used to skateboard and is pretty short for a 15 year old. it could just be there diets or like the others said: skateboarding too much could mess up your back (spine) and knees
cuz skateboarding too much could mess up your back (spine) and knees, so basically messing up your growth. The friend of my friend is a skateboarder and he is 19 and he's only 5'9" 1/2 and his parents are like really tall, his dad is like 6'3" and his mom 5'10".
coincidence easier to balance
i was watching the x games and most of them so far are 5'6-5'7 why is that
