It's a fashionable 'distressed' look that started maybe eight or ten years ago in Italy. The suede gets rubbed with fat (something like 'Dubbin') and burnished. The technique is not dissimilar to the 'wax calf' in classic riding boots. Here the leather flesh-side (rough side) out gets covered with fat and then smoothed with a deer bone and elbow grease to get a high shine.
It has nothing to do with the construction. Resin-based stiffeners have been used for the last fifty or so years and millions of conventional suede shoes have been produced since.
Call it what you will: a 'fashion', a 'craze', 'design'. You either like it or you don't. But once you've got a pair of shoes that have been treated like that, you're stuck. That look cannot be removed, once the fat has soaked the suede it stays in there for good.
