HELP! How big are Fat Face large slippers?

[bigTillyMint]

OK, I know they are large, but I can't find anywhere that says what size that is!

size 7 to 8

Oh, damn. Too big, and no mediums left

They are quite little for a 7.

It's these - do you think I should risk it - I'm a 7 in ice-skating boots

They are quite fluffy inside but 'give' after wearing for a while. If they don't fit then you could send them back.
They look super cosy.

Think I might wait till I go to the sales and try them on if there are any left - can't be bothered with returns!
