0'. The grey/black is a forever classic—so clean. Immediately on feet, you feel that secure, locked-in fit. Compared to brighter pairs, these look "sharp" in real life, on camera, everywhere. The major advantage? Timeless versatility. The downside? Like all 1s, the break-in period isn't the most plush. For $170 USD, they're a wardrobe staple. Perfect for anyone wanting a premium, goes-with-anything sneaker. Not ideal for comfort-first runners. Now, the not-so-great stuff — gotta be real. The main drawback? That break-in period. The leather can be stiff at first. Also, breathability is... not a thing. Your feet will get warm. If you prioritize supreme, all-day comfort above all else? This might not be your #1 pick. It's a style-first, comfort-second kind of shoe — always has been. On-foot feel update after a full day: The Jordan Air 1 breaks in! That initial stiffness softens up around the ankle. They're not "heavy", but you're aware you're wearing them. The real win? The compliments. No other shoe in the Jordan series gets recognized & respected like this one. It's a conversation starter – every single time. 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.
