Let's look at practical things.
Can you tell me what the boots, along with the spacesuits were made of, and what radiation protection was built into the boots, and suit, and their thermal tolerances?
Here is some information that you might consider:
"... This boot is part of the pair that was made for and worn by Eugene Cernan, commander of the Apollo 17 mission that landed on the moon on December 10, 1972.
The International Latex Corporation made the boots which were part of Cernan's extra-vehicular (EV) equipment. The EV boots were worn over the boots that were integrated into the spacesuit and which included the pressure bladder and thermal coverings. The boots were made with a silicone sole, woven stainless steel uppers (Chromel-R), and included additional layers of thermal protection and beta felt in the soles as protection against extreme temperatures and sharp rocks on the lunar surface.
"Chromel-R" is a metal woven fabric. Beta felt is a Teflon coated Beta cloth (glass fiber).
"Chromel R, a nickel chromium alloy fiber developed by Hoskins Mfg. Co. in the mid-1960s, was used in the form of a woven-metal fabric to protect the astronauts’ legs from hot gases produced by the astronauts’ maneuvering unit. These materials would also be used in the subsequent Apollo program."-

"... The 1967 tragedy in the Apollo program led to major breakthroughs in textile science and engineering. The cabin fire that killed Gus Grissom, Edward White and Roger Chaffee during a launch pad test directly led to the development of the Beta glass fiber by Owens Corning Fiberglas Corp.
The company had been experimenting with an ultrafine glass fiber when NASA’s Johnson Space Center contracted it to further the development of ultrafine fibers. The result of this work was the development of a glass fiber with a 4.8 micron diameter that became known as Beta fiber in the aerospace community. Both NASA and Owens Corning invested in this development.
Owens Corning built a full-scale production plant after the successful development of the finest glass fiber ever made. Beta glass fiber was used extensively in the Apollo spacesuit and many other applications through the Apollo and space shuttle programs. The production plant operated until the mid-1990s when it was dismantled. Aerospace agencies had been the only customers for Beta glass fiber over the decades, and the consumption of the fiber was insufficient for the company to sustain the operation of the plant. ..." -

"... The inner layers consisted of two layers of Kapton followed by five layers of aluminized, perforated Mylar. The Mylar layers were separated by four layers of nonwoven Dacron followed by an inner liner of Teflon-coated Beta cloth. Two layers of Nomex felt in the sole ..." -

I did not see any radiation shielding mentioned in the making of those boots - at all. Silicone, glass fiber and 'stainless steel' are not radiation shielding materials. Galvanized Steel can block some EMF radiation.
"... One concern about gamma radiation is the possibility of too much crosslinking. Additional crosslinking may deform the product and decrease its flexibility and tensile strength as well as increase the durometer of the silicone. Bond rupturing also occurs in extreme cases. ..." -

Additionally, When those boots (and the compositional materials, especially the outer most external material) were in direct contact with the lunar surface on excursions (EVA's) for several hours at a time -
https://en.wikipedia.org/wiki/List_of_spacewalks_and_moonwalks_1965–1999 while in direct sunlight, and in shadow, what radiated the heat (sunlight and surface temperature -
Lunar Temperature - Lunarpedia ) and cold (shade and surface temperature) away from the soles of the astronauts feet?
Would that boot material, under standard earth conditions crack, warp or deviate in form (shrink or expand, and to what extent) under similar temperatures and durations?
Can we see a demonstration of such a boot test from NASA of those historical footware that are on display, showing that they are capable of withstanding such temperatures and their extreme ranges.
"... Museum conservators try to extend the life and integrity of objects that have become fragile over time. The fragile interior rubber bladder layer and woven Link-Net restraint layer of this suit mean that it needs to be displayed with as little weight as possible pulling on it. Because the boots are sewn onto the legs of the suit, a reclined display removes that additional pressure. ..." -

If those boots really worked so well as claimed on a lunar surface, then why wouldn't they work on Martian ones or future lunar surface EVA'S, and why the need to redesign them? The only 'boots' utilized now are for non-walking EVA's -
