I am thinking about getting DD the Payless 'crocs' because she's weird and she will love them. The thing is though, she has more than enough sandals for this summer so I am going to get them now for next summer. How much bigger do you think I should go for shoes for a year from now? If I have her try some on now, should I go 1 full size bigger for next year? I know this is impossible to predict, just looking for ideas. Even if they are a little small, she will say they are perfect and refuse to let me throw them away (learned that lesson with slippers this year).
