We say:

To help you select the correct size we have measured the maximum internal length of each size of climbing shoe. Before ordering please measure the length of the child's longest foot (back of heel to end of longest toe) and then select the most appropriate size from the list below.

The UK size range looks a little odd because these climbing shoes are made to European sizes and and each shoe is designed with the adjustable heel to cover two sizes. The size shown below is the converted UK size. As always climbing shoes sizing can be very different from everyday shoes so we recommend that you use our internal length measurements to help you pick the correct size. Don't be surprised if you end up buying one size larger than you child's normal shoe size.
