I feel 440 are 100% 0.5 size up from your normal size. Toe box is square and wide but it's not that wide. You need a 0.5 size up unless you have slim, dainty feet, in my opinion.
If I had gotten size 11, I would have had to return them for being too small. I got 11.5 in these and they fit perfectly. Snug but not crammed.
For reference, I'm an 11 in Accel Slim/Plus, Silo, Dunks/Blazers, Vans, NB 913 and an 11.5 in Marana, Joslin, Legacy Slim, Kalis S, NB 255, 533V2, and 288.
Hope that helps anyone still trying to cop some 440s
