"Bought a pair for my youngest (sherbet apples) in her shoes size, but they were far, far, far too big. Fortunately I always make them wear shoes in the house for a 'trial run' before wearing them out. But when ever she tried to walk in them her whole foot would actualy come out of the boot, and she would be left standing on the leg part! She really loved these wellies so I finally managed to order a size smaller (blue spot) and they are fine. Also ordered a size smaller for my eldest and they fit great. Both have plenty of growing room so will last well into spring next year."
