MizunoWomen's Wave Lightning Z6 Volleyball Shoe

Are these meant for outdoors?

Are these in mens sizes or women’s? I’m seeing mixed answers from the reviews below.

are there any in size 5? i’m about a 5, 5.5 and most almost all the shoes under this brand only start from 6 and i don’t think i’d be able to fit a 6

Whats the width sides .
