"Anonymous. Tell me where this is wrong if it is.
I am standing on a block of wood 3 inches high. My toes are touching the floor. You are on a block 1 inch high toes on the floor. You will rise a grand total of 6 inches. I to equall that will rise a grand total of how many inches ??"
Under your proposition, I would rise, 6 inches, to an altitude of 7 inches.
To literally match my rise and fall, you would have to rise 6 inches also, leaving you at an altitude of 9 inches.
See it doesn't add up - either we will rise different amounts, or we will end up at different ending altitudes, in which case you supposition that there is a proper ankle angle that is common to both man and lady is false. I think it's quite likely that we often will want to rise different amounts, but it's not always the person with the higher heel who should be doing less rise.
(9 inches of foot rise seems a bit extreme - are you a ballerina in pointe shoes or brand new unbroken in ballroom shoes that are stiff enough in the toe box to act like them? )
