short and stout

I already got my rain boots! The fit is perfect, but now I'm trying to decide if they look like they are from the kid's section since they are shorter than the adult version?
They hit about 3 1/2 inches below my knee. Too short????? The only option would be to return, because I am for shizzle not paying $125 for the taller version.

EDIT: Meh... I've changed my mind. These are going back. I'm not spending this much on shoes that I can't decide if I like. Farewell, purple wellies.
