Performance basketball players should choose modern models. Also, if you prefer low-profile, minimal sneakers, the AJ4's chunkiness might not be your vibe. It's a statement piece. Putting these on, the fit is true to size for me. The Air Jordan 4 isn't the most cushioned shoe ever, but you definitely feel that heel Air unit. The lockdown is good, and they're not too heavy. A comfortable, classic basketball sneaker feel.
