Roll about walker for safety walk

After so many years we’ll meet again my old friends in our hometown. She suffered under motorcycle accident and affected her left foot; she has used crutches to help her walk. I think she must be comfortable and safe if she use roll about walker. Because it well helps her for her safety walks. Anyway, I feel so sad when I saw her condition, because she is a gorgeous girl and aside from that she is a very kind person and a good friend to me.
