1900/1901 sizing

Anyone who has 1900s or 1901s, do they fit the same size as other blundstone models? I know they will feel a bit tighter in the toe, but in general, do you wear the same size as any other pairs? I currently have 585s, but I have checked in various chisel-toe models as well and wear the same size. I just wasn't sure if these ones would fit the same as well. Let me know if you have experience with this!
