The breathability isn't great; your feet will get warm. Also, that firm midsole cushioning I mentioned—if you want plush, cloud-like comfort, look elsewhere. The toe box creasing is also pretty inevitable on these. It's part of the charm for some, a deal-breaker for others. Now, potential cons... The toe box creases easily, that's just the nature of the leather. Also, if you have a really wide foot, the fit might be snug. And like I said, if you're used to modern, bouncy cushioning like React or Boost, the Air unit in these might feel a bit dated. It's something to consider. Now, a potential con: the creasing. The soft leather on the toe box will crease, and it happens fast. If you're super obsessive about keeping your kicks pristine, that might bug you. Also, the ventilation isn't great; it can get a bit warm. Just keeping it real with you guys. Putting these on, the fit is true to size for me. The Air Jordan 4 has a snug, secure feel around the midfoot, which I like. The cushioning from the Air unit in the heel? It's decent for casual wear, but don't expect ultra-plush, modern comfort. It's a firm, supportive ride that's perfect for all-day wear without being bulky.
