I'm a guy going through puberty and i've been getting hair in unwanted areas such as my hands and feet. yet, both my parents don't have this problem. do these go away by themselves after puberty? or will i have to shave them?

Likely genetic issue: Where your hair develops/grows is defined by the genetic blend your body has & the tissue/hair response to hormonal influences. The issue is not as simple as one or other parent as these can skip generations or represent a new pattern. Whether you shave/use depilatories or just let it be is your choice. See a doc if you wish to check it out.
