I'm hoping you lovely mumsnetters could recommend me somewhere to buy some slippers for my Nana. She turns 90 next week and is currently having serious problems with her legs and her feet, they have been swollen for a long time but they are currently worse than ever and are absolutely huge. She needs some new slippers but we are struggling to find slippers that will fit. She is also blind so something easy to get on but secure once they are on is essential. Can anyone help?
