The air unit in the heel is noticeable, but the forefoot is firm. They're not uncomfortable, just "substantial". You feel the weight (which isn't crazy, but it's there). The leather started to crease naturally – which I actually like on an AF1. It adds character. Just know, it's part of the journey with this model. On foot for a few hours now. The break-in is real – they start a bit stiff but are molding to my foot. The arch support is decent for me. They feel secure. Walking on pavement, you feel that Air unit in the heel, but it's subtle. Again – not a performance shoe! It's a lifestyle icon, and for that role, the feel is exactly what I expected. Sizing up the details: the leather is smooth, the perforations are clean. On foot, the comfort is adequate after break-in. Visually, it's a masterpiece of simple design. A key "advantage" is durability - these will last years. A "drawback" is the lack of breathability; your feet will get warm. In my opinion, it's a must-have for classic style lovers, but not ideal for hot summer days or wide-footers without going up a half-size. Putting them on, the fit is true to size for me. The comfort is immediate—the padded collar and that air sole unit give a "really" familiar, supportive feel. They’re not "lightweight" sneakers by any means, but you know that going into a classic "Jordan Air Force 1". For all-day wear? They're great, but maybe not for a long walk.
