What's in a shoe? Lots. A lot of thinking, creativity and hard decisions go into the production of a shoe - especially atheletic shoes. Research is required to find materials that are both lightweight and strong, as well as finding ways to minimize the shock of impacts that will inevitably occur. Customatix has developed a material they call Damlite (because it's, well, damn light!) which really absorbs shock well while being lightweight. But enough of the feature hype. You want to know how good they are.
Besides the fact that they look however you WANT them to, they are very comfortable and are made to skate. Customatix's Railers have an above average amount of padding inside the shoe, to keep your shoes in place and under control, while providing added impact protection for your feet. This extra padding causes the shoe to be a bit tight feeling if you're not on your feet for an extended period of time, but the Railers are extremely comfortable when standing.
Additionally, Railers have a nearly completely flat sole. The padding makes up for the difference between the flatness of the shoe and the contour of your feet, but the completely flat bottom of the shoe allows for better contact with your 'board.
