To make sounds for footsteps and other movements of a man in a hazardous materials suit: Record, fairly closely, the sounds made by flexing an “accordion folder”. (Not sure what the proper name for these is. They’re meant to hold papers, the sides are creased like an accordion to allow the folder to expand when it is very full) Next record some squeaks of rubber-soled shoes on linoleum. Don’t walk, just kick your shoe into the linoleum for the squeaky sounds. Extract the bits you like and add the shoe squeaks into the accordion folder sounds for footsteps.

I recorded myself messing about with a glossy-cardboard accordion folder… wish I knew the proper office-supply term for these things. Then I added just a few squeaks from rubber soles on linoleum.
