Help with Birkenstock boston (clogs) sizing

[Sorryfornamechanging]

Does anyone know if these come up the same as Birkenstock sandals or if you need to go bigger/smaller?

I’m looking to order a vegan pair of these for summer but my usual shoe size is 4 (37) sometimes a 3. I’ve looked at my two current pairs of Birkenstock sandals and they both have 35 printed on the inner soles.

Would this be a 2.5 on the Birkenstock site?! I can’t think why I would have ordered 2.5 previously but it obviously worked as they fit. I can’t see 35 as an option on some sites at all.

Yes - should be the same. I have some size 7 (40) in Bostons and Arizonas, and another pair I've forgotten the name of. On the Birkenstock site there's a toggle on the size drop down to switch between UK and EU sizes, so I'd just order them in 35 and not worry about the conversion. The do size very differently from other shoes in general.

I’m a UK 4 and have Bostons in a 37. I don’t have sandals but have the clogs in suede and in leather.

I wear a 4.5 or 5 in a shoe and my Birkenstocks are 38 narrow. I have Boston felt clogs and Arizona sandals.
The Bostons are roomy enough for thick socks, but length wish are perfect.

I'm a 5 (38) and wear a 5 in birkenstocks, both sandals and clogs.

I wear Boston's and arizona's in the same size.
