My mom has some kind of burning feeling on the sole of her foot. but, if she wears certain kind of slipper then she does not feel that much of burn. what kind of slipper will help her to reduce those burning feeling?

Wool slippers are recommended for your mother. Cotton slippers make one sweat and cause a burning and itching sensation.

The burning could be the result of an entrapment of the nerve in the tarsal tunnel if the slippers that provided mild relief had support to the arch , a slipper with more support might provide relief A podiatrist is recommended to be seen.
