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. Potential con? The comfort, for sure. If you're used to React or Zoom, these will feel flat and firm. Break-in time is real. Also, the toe box creases – it's part of the story, but some people hate it. This isn't a performance shoe; it's a lifestyle icon. Keep that expectation in check before you drop the $180 USD. Sliding these on for the first time... okay, let's be real. The Jordan Air 1 is NOT a comfort shoe. If you're coming from React foam or anything modern, you'll find the footbed pretty firm – almost stiff. The ankle collar, though? It provides great support and that classic, snug wrap. It's more about style & statement than all-day cloud-like comfort, for sure. Let's talk comfort — realistically. The "Jordan Air 1" is "not" a modern performance sneaker. The cushioning is firm. If you're used to React foam or Air Max bubbles, you'll find these pretty stiff, especially for long days on concrete. That's the trade-off for the look. The plus side? That firmness provides great stability, & the leather upper will mold to your foot over time for a better fit.
