I too am awaiting reviews of this shoe with bated breath, it looks almost too good to be true! Interesting to see which UK outlets have the shoe, you'd have thought the big chains would have been all over this one ...... but no!
For what it's worth, I checked out Road Runner Sports (the world's biggest running shoe outlet) and they have the Cesium retailing at $120, so for those who can't locate a pair it might be worth the shipping costs. The forecast UK price is about 85 quid isn't it?\
I've just looked again and RRS seem to have very limited sizes, so perhaps supplies of this shoe are hard to come by. Look at www.roadrunnersports.com.
