they should end up with the same size shoes whichever shoe shop you are in and regardless who fitted them. I took my 4 yo DD2 to get new shoes last weekend. We have been getting her feet checked in her old shoes for a couple of months and kept being told that they were fine so we waited (I begrudge buying a new pair in the same size as the old ones). ANyway, we went into Clarks and she was measured as a 9E but could just about make do with an F - we weren't happy with that and they said that they had nothing in that an E but were told that they could order a pair of boots in for us. We didn't really want to wait for a week so they sent us to 2 other shops who sold Clarks shoes (amongst others), they both told us that an F was far too big but one shop thought she needed a 9 and the other a 9 1/2 E, (neither had anything that actually fitted) we eventually went back to Clarks where she was fitted by a different sales person who said that she needed a 9 1/2 E but the boots we wanted didn't come in an E fitting (even though the original sales person had been to check !) so we had to buy something completely different. I know that the sizing gages are only a guideline but how can 2 people in the same shop try the same pair of shoes on her and come up with 2 different sizes. AIBU
