Venturi Tre here! So far I only wore them and walked around. I have wide and flat feet. On top of that, I may have 1 foot that is slightly bigger than the other. I struggle to find 15s and obviously no one makes 15.5. Many if not all of the size 15 hoop shoes I tried on are slightly too tight, 16 are comfortable but gives too much space. These shoes are a perfect fit. Normal feet, scale down a half size. Big fellas will be fine TTS. Materials feel thin but I still felt secure walking around. Will leave another review after a hoop session or two. Thank you Adidas! Peace!
