Strange Reflection Problem

Geminii23

Hi.  So I have been using this environment for a long time and have never run into this before, but for some reason the boots (Urban Edgy outfit) are invisible in the reflection on this render.  The floor is actually the Plexiglass prop that came with Fashion Studio environment.  I believe there is something wrong with the settings of the boots themselves because when I try a different footwear item it works fine.  Any ideas on what I need to change here?

Thanks!
