I've never understood luxury sneakers, save for maybe arenas. A lot of them are derivative forms of popular athletic brand sneakers...what is the appeal beyond the label factor?
Plenty actually, outside of style, shape and quality, silhouette plays a huge part. This is something kind of hard to understand or explain unless you have both in hand.
Branding as well, yes Gucci and LV tends to have outlandish monogram and makes you a walking billboard but most are very minimal as well such as CP, SLP, Margiela, etc... Nikes and Jordans tends to have their logo plastered on the shoes, many wants an alternative that doesn't have that.
Let's get it out of the way now, yes you will pay a premium for the price, that's just how luxury brands work, I've beaten this to death but luxury items aren't exactly a responsible purchase. It's a "want", not a "need."
Furthermore, they aren't always derivative a popular athletic brand, I mean IIIs and XIs are arguably the most famous of all sneakers ever made in the world and there really isn't a comparable pair int he high-end department, well Lanvin kind of made their own IV version but those didn't sell so you can't really always say "you only buying because it's a more expensive pair of these".
Actually come to think of it, outside of the classic designs like Stan Smiths vs. CP Achilles/SLP lows, there really much that are an alternative to each other when it comes to popular athletic shoes? I mean Raf has a Vandals look a like but you can tell how much better the Raf version looks in comparison to Nikes. It's the minimalism and sleekness that works for the Raf while the Nikes already looks beat and bulky and has that huge swoosh.
