KD 7 true to size?

hi guys, im size 9 

i own a pair of kd 8s that needed to be half a size up      sz 9.5

note:when wearing kd 8 size 9, it was super snug.

what should i expect from kd 7?

where im from they dont have kd 7s anymore, so i cant try it on

do i need to go up half a size like the kd 8s or does it truly fit to size as many reviews say so.

just by looking at both toe boxes...
the kd 8s look narrow
the kd 7s look square

thank you.
