Highest quality sneakers are probably Buttero. They even use vegetable tanned leathers http://14oz-berlin.blogspot.fi/2012/05/buttero-sneakers-made-in-tuscany.html CP's feels quality-wise better than both the original and Margiela's GATs e.g. leather and construction. For me, when talking about sneakers, design is pretty much everything that matters anyway. I like Raf velcros and vandals most.
