I bought these for my step mother who is in her 80's. She has arthritis in her feet and told me she had to stop wearing shoes and resorted to slippers soft and loose. I purchased a shoe size larger than her actual size to allow for "wiggle room," so her arthritic toes would not have any pressure. She wrote me and told me she is now pain free with her walking and that her feet are toasty warm in the Winter. She was 100% pleased and happy with these boots she thought she could never wear but now wears them everywhere. Thank you Keen.
