I have been buying Totes isotoner slippers for my DD which were brilliant as they stayed on her feet, were nice and cosy, and with her high bridge were a good comfy fit. However, now she is wearing through the soles too quickly so I need to find some slippers with firmer soles (that are non-slip) but are roomy enough for her high bridge. Other slippers I have tried seem to squash the top of her foot. Clarks online reviews aren't good and shops seem to have lots of cheap looking pairs which I am not sure will last. Any ideas please?
