Bought a pair of crocs style shoes from poundland. My 2 year daughter is size 4.5 and we picked up the stated size 21 for her....they had other sizes from 21 going up. About 5 colours (black, green, white, red, and another one i cannot remember).
Looks very similar to the cros and the little one loves running around in them in the garden...
This was in the Poundland Basingstoke.
Searched for this but could not find the deal...sorry for any double posting
