The shoe as a whole will be noticeably beefier. Just all around a bit bigger in bulk than the original but the sizing fits the same as the original. I've always ordered a 10.5 in the originals as I do with all my vans and it's the same with pro's. Same can be said with the slip-on pro's (of which I've skated heavily.
Might get the back of your heel rubbed raw if you don't hit these joints with a heat gun to soften them up because the heel protection is noticeably stiffer than the originals.
And to finish it off, the entire shoe is suede, at least the all red version. Which I like because my pink slip on pro's have canvas around the outside of the color which I don't care for since it rips way easier than suede. Also under the suede in the toe box area will be a layer of rubber I believed to be Duracap. Super nice when you bust a hole through the suede. And a remarkably comfy insole. Up to par with Nike's Lunarlon.
I was not endorsed or pursued to write a review, I simply wrote one because I wish there was one to better conclude my purchase before buying. But it was well worth the buy. Cannot wait to destroy these puppies.
