The Air Jordan 4's upper doesn't have much ventilation. If you're in a hot climate or plan to wear them for long, active periods, your feet might get warm. It's a trade-off for that structured, supportive feel. Just something to keep in mind, depending on your needs. Now, a potential con: the toe box. It can crease pretty noticeably. Also, that firm midsole isn't for everyone—if you're on your feet all day, you might want more cushion. The price, $210, is steep for the tech you're getting. Just being real with you guys. Comparing it to other Jordans? The Air Jordan 4 sits between the AJ3 and AJ5 for me. It's less bulky than a 5, but has more structure than a 3. The cushioning is firmer than an AJ1, for sure. If you like that retro, supportive build, this is a great pick. It's a cornerstone of the Jordan series. In summary, the Nike Air Jordan 4 'Military Blue' is a win. Great looks, wearable comfort, and iconic status. It has its minor flaws in breathability and a firm ride, but the overall package is strong. If you've been wanting a clean, classic 4, this is a great choice. Go for it.
