Seems you are already on to the old problem re stilleto heels.
Did carpets help to solve that one or was there another solution?.
Then there are the floor support structure design specs.
These have probably been changed lately to account for floor collapses following explosive decompression pressure imbalance should a cargo door come open. May have been provided for by adequate floor vents.
I think you have opened up a new can of worms.
Should be some interesting illuminating responses.
See you again soon on the Yaw/Asymmetric/Sideslip thread.
