Cool guys. Thanks for the info! Cleanest and Egaroc, would you say that applies to all AF1s, or just lows like Coordinate says?
I'll probably head into a store to try a few pairs on.
To weigh in further, I noticed anything from the mid to late 2000s definitely run .5 size big. Recent pickups have been mixed, some tts some .5 size big. All my Nike ID lows from this year, are TTS. Which is a little confusing.
I think the reason is the GRs are pushed out in large numbers and they just lose consistency on the specs.
A friend of mine manages product manufacturing and explained it to me. They have measurements they require for quality control, and everything that comes out has to fit within a certain window of that measurement to pass.
It cuts costs to be less stringent. For instance, if the target is 20cm long and it comes out at 22cm, they could still pass it and not trash the shoe. However if they want to be particular because they expect the customer to be particular, then they could say it has to be exactly 20cm or it fails. That will lead to more product waste and therefore cause the shoe to be more expensive, or they have to spend more time per shoe to get it right the first time which also drives up costs. Either way it drives up costs to be more precise.
I highly doubt your average GR for 90 bucks in Footlocker gets held to the same standard as an ID or special release. Hence the discrepencies in sizing.
