Hi. My DD has asked for Dr Marten's boots for her birthday. She wants the classic ones, 1490 I think? I have never worn Dr Martins but always hear people talk about how painful they are to begin with. Do you think they're suitable for a child? They're not cheap but I think she'll be able to wear them for a long time. Does anyone know where to get online for the best price? DD's feet are size 5.
