Pretty sure the Vans ones are just a slightly different variation on the Wafflecup sole. It's not the same one as on the Crocketts or Walkers, but same idea. The uppers appear to be the standard Sk8 Hi and Old Skool pro, with a small rubber patch on the inside of your foot (I don't ride BMX, so I don't really know what it's for). I haven't tried them, but I'm sure they'd skate fine. Probably just like regular Sk8 Hi's or Old Skools, but with the sole like 1% more supportive (Wafflecup is still too thin for me). I've seen a few pros in them - I think Daniel Lutheran was wearing the Sk8 Hi's for a bit.
