Correct me if I’m wrong, but the High Snobiety and Gold Medal Ultra Boosts are the only released pairs that feature a leather cage, right?

I think that’s correct. Nonetheless, adidas will release a Core Black 3.0 with a new cage. Not only does it feature a leather cage, but peep the heel counter. That’s new too!

There’s no release date, but I expect a release date to surface sooner than later.
