I don't think so...I'm not familiar with either the movie or the Steinbeck novel but a search of "tenuous shoes" on Google brought up 3 hits and one was actually a misspellt "tennis".
I haven't seen the movie, but I very much like the novel. "Old Tennis Shoes" was what the "boys" in the story called Old Tennessee, a brand of whiskey they favored when they could scratch together enough coin to afford it.
"Old Tenuous Shoes" sounds like it could be something in a bottle (tequila, including worm*?) featuring in a yet-to-be designed bit of starship Photoshoppery. ¿Tenue Zapatos Viejos?
