These fit my 3.5 year old perfectly. We ordered a 9.5M because shes in between a 9 and 10 right now and the sizing is exactly what I expected for a half size. The shoe seems sturdy with a stiff back that does not collapse but is flexible and bends when my 3yo walks... she said they are comfortable. I like that these are washable... I will update after first wash if they don't come out well or if anything disappoints with quality later on. The only reason I am giving 4 stars out of 5 is because the opening is somewhat small (tongue is attached). Easy for me to put these on my daughter, but at this shoe size/age a no-tie shoe like this should be easily put on by the wearer and the small opening makes it difficult.

Update: these DID NOT wash well. Insert came out and fell apart and can it be put back in due to it being shredded. I washed in the machine with extra water on cool/gentle. Bummer.
