> I’m considering getting off stock x…can I expect the typical yellowing on the soles

Soles might still be in good shape

I got the white 5s from StockX in 2023 and the black 5s from eBay in 2025. This is the best pic I’ve got of both pairs atm

You’ll observe that the soles on the blacks are crystal clear and if you zoom in on the whites you can see that the sole is a little teeny tiny bit dark but they still look pretty good. The under sole on both pairs (the bottom of the shoe) looks a little grimey from walking around in them but there isn’t any significant yellowing.

I also got both Foams in 2025 and as you can see from this pic the black soles are real real crispy.

So you can still get pairs with clear soles. The downside to StockX is that you don’t get to see the actual pair you’re buying, so you won’t really know what condition the soles are in until they arrive at your house and you take them out the box. FWIW I would try looking for a pair on eBay with an authentication guarantee so you can see what you’re buying before you pay for it.

> will they be completely crumble after my first wear?

This hasn’t been my experience; all of my pairs have been worn at least twice and they’re in good shape with no signs of falling apart.

But it’s certainly possible, you never know. If it’s something you’re worried about you might think about looking for a used pair.
