Just when you get familiar with one of Nike and Sacai’s experimental sneaker creations, the formula changes. In the case of the latest VaporWaffle, it’s the upper that’s different, with deep violet leather replacing the previous pairs’ mesh. Everything else is as normal — that is, if you could ever call a release by these two normal. Accenting orange picks out one of two Swooshes, and there’s double the tongues and laces, too. Underfoot, the model’s signature sole unit is stacked, split, and jutting out at the heel, as always.
