My 7 year old daughter usually wears a size 2. I ordered a size 3 because I saw reviews saying they run small. THEY DO. I should have ordered a size 4. Please order 2 sizes up when purchasing this shoe.My daughter asked for a pair of Birkenstocks to match her aunt. She wanted the pair with 3 straps and no back. She got them yesterday in mail and was so excited these are her school sandals she wore then all last night!The only issue is that they seem to run a little short. The color was really pretty and delivery was quicker than expected.The sizing is so messed up! My daughter wears a 2.5 so I ordered a 3 since they do not offer half sizes. The 3s were a tad too small so I ordered another pair in size 4. The 4s also seemed a little too small and upon comparing them I could see that they were less than 1/4 inch bigger than the 3s. I went ahead and ordered a third pair in size 5 and they were the exact same size as the 4s. The photos I included show first all three pairs side by side - 5, 4, 3 from left to right, and second I held the size 3 up against the size 5 to show the size difference. I am so frustrated and confused!I am adult who wears a size 2.5 kid's shoe, since women's shoes in a 4-4.5 are not available in a lot of styles. I bought the sizes 2 & 3, but both were small. I have since ordered the kid's 4 and women's 5. I want to like these, but it's taken a lot of time to get it right.My daughter loves these. She says they are very comfortable. I ordered one size up after reading the reviews, but had to exchange for bigger. Save yourself the time and order 2 sizes larger!I purchased these for my 9 year old daughter after getting some of this same brand for myself. These are the only sandals she will wear. She says they are very comfortable and keep her heels from hurting. They are well constructed and can be worn with almost anything!Tal como se esperaba, son muy lindas y resistentes. A mi hija le encantan y la talla va super bien!! para el precio inmejorables
