Thanks for the reminder - I'm Umi mad, me!
I always buy out of season and have never paid more than £15 for any pair (apart from the Odessa boots which I paid £16.50 for in Feb and they are now £55!)
They are a tiny bit on the smaller side due to the padded soles and sides but that's a big bonus. They are continental sized on the box and I have occasionally got a 23 or a 24 when ordering a UK 8 - but returns were free and no big deal.
