Well The polystyrene will do just as good as my thougt. I was think more along the lines of stinkyattic. Snowshoes or do you have to wicker chairs if so take the backs of them make sure the you keep the out side wood on there to glue or tack rope,wire,bungee cord,and or phone line to keep them on your feet. you could also put some polystyrene in the bottem of them to make your feet wider no prints at all.
