Ugg boot sizing

[CityRd]

Last bought a pair 10 years ago and if I remember I had problems with the sizing.

Do I go up/down a size or take my usual?
I'm after the Classic Tall II and usually a UK4.

I want to get a pair of Ugg boots and want to know if they come up true to UK size? I want the flex boots but am scared to order a pair incase they don’t fit..
Experience any one?

I think they are a half size up. I’m a 4.5 and my Uggs are a 5. I also had 4s but got holes in the big toes. On the other hand my running shoes are a 5.5 so who knows.

True to size

I seem to remember there was a bit of faff about sizing on their website. Mine are labelled 6/39 and US 8. Whereas my Nike trainers say 6.5 / 39 and us 8.5. I'm usually a UK 5.5, 6 if no half sizes. the 6 is perfect for me (I don't wear socks with them) So I guess I'd go up if in doubt.

True to size, I work with them and have also owned boots and slippers in the past

I'm a UK 7 and I had to get mine in a US 9.

This was about 15 years ago
