These run large. Apparently they run larger than the round-toe Blundstones. I normally wear a US 10, and a 9 in these was too big. I ended up with an 8.5. It fits the same as my size 10 American shoes, and my size 9 UK Clarks. These have a fairly wide toe, so the fit is forgiving.

The insole is not great, but there are plenty of replacement options for it.

I was worried that these would be difficult to get on, but they are actually harder to get off. I think they will loosen up a bit with wear.
