This is the second report we have gotten on her wearing shoes which could come off easily (KK). Why they put tennis shoes on the missing poster is beyond me? I guess it is possible her mom didn't notice what she was wearing and couldn't find her tennis shoes?
This is no different than JVK talking to M or Scandi talking to FV today. It is fine to report it if you are the person talking directly to them. You can feel free to report the whole conversation...at your discretion of course.
Another way to look at it is why does KK keep insisting that Lindsey was wearing slip-on shoes if she was wearing regular sneakers.
IIRC, when she mentioned it to jvk, she was making the point that if Lindsey had been grabbed on the street, her shoes would have slipped off and been found.
