Seemed like he fit really well on Vans and they were hyped on him, since he's had like 6 shoe colourways and a bunch of apparel. I don't know the guy, but he seemed hyped to be on Vans as well. I can only speculate (and I will speculate), but this feels like a thing where his contract came up and Vans just wasn't willing to write the cheque that someone else was. He's an extremely marketable skater right now, and there was all that stuff recently about budget cuts and layoffs and stuff at Vans, so it was probably a tough time to get a big raise for a skater over there, even for a guy who probably more than earned it. Hope he gets on something cool and makes big money.
