For reference I have the EP versions, I'm a US9.5M in this model (Narrow feet), the shoes have a narrow midfoot area and lots of Toe box space. Tried on a 10M and fit like a 10.5M for me.
I'm a size US 10M in Regular Nike/Kobes (including the Protros)
Sabrina 1s have more space in the toe area for me compared to Tatums in the same size. Yeah, i meant narrow in the arch area.
Agree, have the Lebron 20s as well in a Size US 10 and they is barely any space in the toe area.
I have narrow feet and got the EP versions half size down from my usual size (9.5) - I'm usually a 10 in Kobe Protros. There is still some space in the toe box area even with the half size down from my TTS.
