"Je voulais des chaussures rouges."
Traduction :I wanted some red shoes.
C'est correct! Il y a juste un problème de traduction sur cette phrase...
Willing is not the right word here. It is not the same thing as wanting at all. Willing means to be prepared to accept something. I was willing to have red shoes. I didn't really want them, I wanted the blue ones but I was willing to accept them.
