My uppers look pristine, and all I do is wipe it down with a damp paper towel. The bubble is getting a tiny bit hazy, but overall my pair look great for wearing them ~40 times.
I got my Undefeated 97s pack last week and the sizing was normal 97 sizing. The toebox is slim/slightly tight so if you have wide feet or like the loose fit, half size up. For most people, TTS works fine though.
