My floor hockey season begins in 2 weeks, I will update then, although I am very confident they will work really well. If I were making a second set I think I would have covered the knee wing too though.
I have received the felt pucks and I will definately still be wearing a c/a and everything else. Little kids shooting them might be ok but I know that adults can crank them so these things could hurt (not injure though of course...mind you with my blood pressure meds I bruise if you look at me hard

)
There is not even one square inch of sportcourt in my town as far as I know, so I cannot help you on that. I don't even know what sportcourt feels like

I will be using these on varnished hardwood.
