The original boots were made using the same approach - they were measured by the seller and then made to measure. They were made by a different supplier.
However the seller re-measured my daughter for the new boots and did not use the previous measurements. In this instance they were too narrow.
The reason for mentioning that her original boots still fitted fine over the period December 2014 to April / May 2015, when her new boots were made and delivered, is that there was nothing of which my daughter was aware that indicated that her legs had changed shape.
