The main one? That flat, firm midsole. If you're on your feet all day, this isn't your go-to "comfort" shoe – you'd want something with more tech. Also, the toe box creases... it's gonna happen, it's part of the leather's charm (or annoyance, depending on your view). So, this specific Jordan Air 1 model isn't for the comfort-first crowd. Let's compare for a sec: the "Jordan Air 1" vs. a modern Dunk. Similar vibe, right? But the "AJ1" has that "height" - the ankle profile is higher, more structured. It can feel a bit more restrictive, but also more supportive. The Dunk is often more flexible out-of-box. So, choose your fit: classic bold (AJ1) or broken-in casual (Dunk). Sliding these on... immediate thoughts? The fit is true to size for me. The "Jordan Air 1"'s ankle collar offers solid support, & the overall wrap feels secure — not too tight, not loose. It's a structured shoe. The insole is pretty basic, though, so don't expect plush cushioning right away. It's more about that classic, grounded feel, which I actually kind of prefer for everyday wear. Final take? The "jordan air 1" is a must-have for any well-rounded collection, period. It's the blueprint. But be honest with your needs. "Love": The timeless design, the outfit-elevating power, the heritage. "Note": The initially stiff feel & basic cushioning. I'd recommend it to collectors, style-focused folks, & Jordan enthusiasts. I'd "skip" it if technical, modern foot support is your #1 concern. Hope this honest review helps!
