Still love the original Sambas (the black leather ones with the stripes in white), am on my third pair now.

Also had a pair of navy Trimm Trabs years ago which I wore into the ground.

LA Trainers are the best looking Adidas ones IMO.

I've never bought trainers for anything other than running.
For decades I maintained a stock of three pairs, buying a new pair when the oldest wore out, usually through compression of the midsole or, sometimes, the outsole just wore out.
What they looked like was almost irrelevant to me, as they'd be a pale-mud colour pretty quick.
Once, at a leaving "do", I listened to a guy telling me which were "the best", "cool" or rare and which were not.
When he mentioned a type that I was quite keen on at the time as being "boring", I told him, without rancour or criticism, why they fitted my criteria and how my criteria were different from his and he looked at me as though I was mad.
Takes all sorts, doesn't it?

Trouble is now, if I wear trainers (I don't) in a social gathering I end up looking like one of those old men you see hanging round bus stations with baggy jogging bottoms tied up somewhere around their armpits.

I'm not a collector but I've got quite a few pairs of Y-3's

Get you!!!!
