I'm 5'11" and wear a 8.5 or 9 shoe, my feet stopped growing when I was 12.
I come from a family of tall people, everyone is tall on both Mom and Dad's sides.
I'm the shortest of all my cousins on my Mom's side, and I'm pretty much even with all my cousins on my Dad's side. I'm an only child so I can't compare to any siblings.
