Probably the most comfortable shoe I've ever owned. Whether you wear socks or not, these feel amazing on your feet. I barely feel any resistance from the ground against my feet. These are perfect for flights because, aside from the comfort, it slides on and off instantly. I always get a double-take from someone when I walk around with these. I don't care what you compare these against, Ultraboost, Uggs, whatever. These will be more comfortable. I should've bought a set. Just get 'em and thank me later.
