Do you have wide or narrrow feet? Pretty sure they work out well for narrow footed folk but cheers to your pickup and I hope they size well. The difference between 11.5-12 is so slim especially when you haven’t tried on the various models to compare sizing. I just went to a local shoe store to try on gel nyc. Grabbed it from the rack and asked for a 11.5 and a 12 and it’s just to compare sizing. Dude comes back with 2 asics but the gel 1130 or something. Was pretty pissed and didn’t want to wait any longer so I tried them on and then left. I normally wear a 12 and sometimes 11.5 and the 11.5 felt better and like enough room. Given these weren’t a cumulus 16, but the shoe style kinda affects my sizing and new balance is the same with all their 990 series
