Mom is 93 and has Dementia. She lives with me, step daughter. She has been here with me to a year and a half. During the summer months she used to wear her flip flops, but now she cant seem to keep them on her feet. So she wears her slippers whenever she walks out of her room, the slip in type with the open back. She shuffles along. I'm wondering if maybe a ballerina type slipper would be better? I think something that fits her snug would be nice. I don't know what kind of sole would help though. If it is too anti slip, the shoe might not move when she does since she shuffles along. Don't know. Any ideas or experiences?
