that is some butt ugly boots and outfit combination if I ever saw one.

Well it was designed by engineers in the 1960s using imperial measurements on a sliderule to keep an all American crew safe in a vacuum 250,000 miles from Earth.

and pretty sure they didn't use a sliderule for the moonboots.

They had to calculate the pressures and temperatures it had to withstand, puncture resistance, and lots of thing regular boots never worry about. With the pressure outside is zero, the suits turn into the Michelin man stiff suits and so to the boots. They had to withstand 260 degree of heat and down to minus 280 in the shade.

My point is.. they did not use the slide rule to design the actual boots.
they have used the slide rule to predict and calculate the working environment for the entire space EVA and moon surface program.. To what the boot, helmet, suit, gloves, coupling, the LEM, the CM and everything else had to work in.
The temps and pressures were not uniquely calculated for just the boots, everything else had to live in that same environment

So once they had done that.. and went about to designing the actual boot
the slide rule no longer was required.. All they had to do is fabricate, and test, and test some more, then retest and you don't need a slide rule for that...
tape measure perhaps.. and pressure and temp gauges for the test.. but not a slide rule..

If you still have to calculate requirements at the time you start designing a boot.. yer just wasting time.
