Don't think this is the one you are looking for, but some good bargains here:

I am watching with interest in case anyone comes up with the right one, although my two are rapidly heading towards adult shoes now . My eight year old now takes a 4 and my 7 year old takes a 3. Between school shoes, indoor school shoes, gym shoes, trainers (astro and normal), rugby/football boots, sandals, walking boots, snow boots, wellie boots and pool sandals or crocs (x2) - it is costing me a fortune! When I was a kid, you had a pair of shoes or boots for winter and a pair of sandals for the summer - if you were lucky you had a pair of gutties as well!
