I'm size 10 US men's. My birks are 42. Also the difference between 42 and 43 is huge. 42 fits right, but I swim in the 43s.

Are you pushing your foot forward in the photos? Try 42, when you're a consistent whole size it's often possible to go a size down in Birks. You're in a spot where the difference between a 42 and a 43 is a whole size rather than the usual half, so it's actually 2 sizes down in this case. Stick with regular width.

I wear woman’s 10.5 - 11 but I wear a 39 in Birkenstocks. I size down one size and they’re perfect

That’s crazy. I wear a women’s size 9 and a 40 narrow in Birkenstocks!

I would suggest sizing down to a 9. Birkenstocks tend to run larger so a 9 might reduce this excess room in the back. If you have wide feet, the wider footbed may be better in the long run

They are definitely too big (long), but you shouldn’t really have to size down at all as they run true to size. US women’s 10 = euro 41; men’s 10 = 43.

Both converse and adidas tend to run true to size or on the smaller size, not like Birkenstocks

Well according Birkenstock themselves they run true to size. I find mine run true to size, so I’m not sure what’s with the down votes. I’m just going on what Birkenstock says, and my own experience.

But how many times have you read a description of something and it didn’t fit anywhere near what you thought? It’s true that their website does say that but I had to size down just like many other people in this sub. I had to try them on in person

Everybody knows birks do not run true to size

Meh, mine do. I think a lot of people wear them tighter than they recommend…but to each their own.
