Everything of the Lunar Module should be as light as possible. Therefore no thick-walled, heavyweight, pneudraulic-type struts were used to absorp the landing shock but lightweight aluminum honeycomb cartridges. Shock was absorbed by crushing the honeycomb cartridges.
The footpads were build as a sandwich structure of a honeycomb core between two aluminum panels.
The aluminum honeycombs were assembled using adhesives, also the footpads. The used aerospace aluminum alloys and the adhesives should not be too hot or too cold, they would loose their strength otherwise.
Landing-gear thermal insulation must maintain the landing-gear
temperatures at or below design levels to ensure positive structural
margins of safety and proper mechanical operation during deployment
and landing. Furthermore, temperature control of the honeycomb energy
absorbers within specified limits is necessary to preclude large
variations in crush-load levels.

According to this pdf, long term temperature of most honeycombs should be lower than 350 °F or about 175 °C.
About 300 °F or 149 °C may reduce strength to about 80 %.
