I think she wears the same shoes everyday and they are worn out.
Aren't shoes to be worn everyday, until they are worn out?
I think that her shoes have been used a lot especially on the left sole.
Sounds like she needs a new pair then!  Nobody should have to walk around in shoes that are falling apart.  Maybe help her buy some new ones?
I would never help her if I knew it was true.
True? the she wears the same shoes everyday. They were made to be worn daily.
