Hey buddy, thanks for the kind words. I bought the F2S's (LOVE this color too) from FNL in an 11 (same size as my Curry 1's) but they were a smidge too tight for my big toe on my right (bigger) foot. Exchanged them for an 11.5 and they feel worlds better. Got the wiggle room I need when I play/workout/walk around.
All depends on your foot and how you like the shoes to fit. My feet are normal and I'm a true 11 in most everything. From what others said earlier in the thread, these are a hair shorter inside vs the 1's. Hope this helps buddy.
