Thanks for the link!
IMO, the difference is that designer versions of athletic shoes - the good ones, anyway - are made of better materials, have better construction, are generally given a more aesthetically pleasing shape, and incorporate small details that set them apart; for instance, Lanvins are typically made of several different materials such as satin, taffeta, leather and (high-quality) rubber.
I have some high top Adidas that I love, and that are pretty comfortable, but they don't compare in quality of materials used, or fit, or support, and they look kind of clunky next to the Lanvins.
Is it worth the premium? That is in the eye of the beholder!
