My mum has asked for some slippers for Christmas. They must have a hard sole and a back. She has suggested that she would like brown suede (but I think this is flexible) and they need to cost around £60-£80?? I've spent hours googling but all the nice ones are slip on.
This thread is slightly old now so some of the suggestions may be out of date, but if you’ve landed here looking for recommendations, we’ve recently updated our best women’s slippers page with lots of great options rated by real Mumsnet users. We hope you find it useful.
