It's just the timing (early afternoon), location, and that so much has come out in the past few weeks. There's definitely high demand for them. When I went to sign-up for V2s at FL EC there was 2 people in front of me and this is at 1pm in the afternoon at the most central location in the city.
With that being said, there's definitely been a shift as far as sneakers the past 2 years. If it isn't an AJ 1 (which JB ran into the ground), hype hounds are only wearing Yeezys, UBs, NMDs, and whatever ill collab or tech shoe Nike came out with.
