If your child wears AFOs you will understand the struggles with finding shoes to fit and how hard it can be getting shoes over AFOs.

These boots made by Billy boots are fantastic !  BILLY Footwear has revolutionized how shoes are put on and taken off. By incorporating a zipper that goes along the side of the shoe and around the toe, the upper of each shoe opens and folds over completely. The design allows for unobstructed foot placement onto the shoe footbed. Then with a flip and a zip, the shoe securely closes.

They’re not available in the UK but can be ordered online from America. They come in lots of colours and styles. I found a good selection on https://www.zappos.com/b/billy-footwear-kids/brand

They are expensive, around £65 with delivery.
