RayJohn,
The biggest issue in my opinion with cross training shoes is they don't offer the same stability (or durability) that tennis shoes can offer. We are seeing tennis shoes go more minimalist, however there is something to be said for some support and stability on the court. I wear Metcons (and sometimes Free TRs) in the gym but personally would never wear them on the court.
Know that when ordering from TW, we do offer free returns on shoes that have not been used -- so we encourage you to get them, try them on and wear them around on carpet to see if they work for you. If not, you can send them back and we'll help you get into a shoe that fits better or is better suited for your needs.
Hope that helps!
Michelle, TW
