My DD claims to be desperate for a pair of Heelys for her 6th birthday - but I'm not sure about what size to get her. Googling them tells me that you need to go up either one or two sizes , but that's not desperately helpful. I am planning to get them on eBay in case her interest in them is as short-lived as I imagine it will be, so don't want to get her all excited by going to a shop to try them on.
She's a size 13 in normal shoes.
Any advice would be very welcome!
