Both .5 size down and TTS fit fine for me, no heel slip. The only thing off with TTS was that the forefoot articulation wasn't in line with how my foot flexes.
I started going off EU sizes for Adidas models and that's helped with fit issues. I'm also a size 10 in all of those Nikes and got a 10 in the Lillard 2's. Could have gone 9.5 for a super snug fit but I like a little bit of space.
Played last night for a few hours. Had a little bit of heel slippage but wasn't anything that prevented me from moving how I wanted. Hoping it's like the 1's where the fit gets better the more you wear them. Glad I went TTS though because I definitely would have ran into the same toe jamming...
Just picked these up from Foot Locker. Same as Jeff, tried on both TTS and half size down, could've gone either way but went TTS. I was on the fence between going half size down but half size down is a tad narrow, the bootie hugs/holds your foot a lot better than the Lillard 1's IMO making it...
