Kids snowboard boots size 5.4-4 ish

Basic blue snowboard boots, nothing fancy like a removable liner but my little snowboarder says they did the job fine. Brand is Freestyle, size label says US 5, UK 4.5 and Euro 37.5 but in reality I'd say they are about just under a UK 4 given Em's feet measured exactly 4 just after she said they were too small.
£10 (cheque preferred given paypal's fees but paypal OK if you cover the fees) plus post at whatever it costs to wherever you are.
