The Air unit in the heel is there, but it's more about impact protection than bounce. The shoe isn't heavy, but you feel its presence. Break-in is real with these; they'll get more comfortable with wear, I can already tell. Putting these Air Jordan 4s on... the fit is true to size for me. The lockdown is decent, thanks to those plastic wing eyelets. The cushioning? It's firm, but in a good, supportive way—you feel that Air unit in the heel. It's not super plush like some modern sneakers, but for a retro, it's comfortable enough for all-day wear, honestly. Who might want to pass? If you're purely chasing cloud-like comfort, look at something like a New Balance or a modern Nike runner. Also, if you have a really wide foot, the fit can be narrow in the midfoot. And if you hate visible creasing on your sneakers, this model might give you some anxiety. Who might want to pass? If you prioritize ultimate comfort above all else, or if you find the $210 USD price tag steep for a retro with simpler tech, you might look at other options. It's an investment in style, not just comfort.
