Replying to Gripwalk ISO 9523 Compatibility

I have some boots with Gripwalk ISO 9523 soles and would like to mount some pivots (probably with the cast system). From what I can tell they are not compatible because the 9532 standard needs a MNC AFD plate that can move because the soles are rubber and have to much friction to release correctly with a standard AFD.

But my boot soles have a hard plastic where the boots will contact the AFD.

So will these actually work with a binding labeled Gripwalk? Are they more like the newer Gripwalk ISO 23223 standard?

Thanks.
