Hello Aurélia,
Sock: it corresponds to the symbolism of the traditional woolen stocking in which one tucked away one's savings. It is therefore related to the idea of a vital energy in reserve, an inner wealth that is unexploited or ignored.
Shoe: a rather ambiguous symbolism: on the one hand, it evokes sexuality (finding a shoe that fits one’s foot) clearly reminds us of this. On the other hand, it represents the right to independence and freedom (slaves go barefoot, as do monks, by renunciation).
The shoe also represents all the mechanisms of adaptation and retraction, all the reflexes and behaviors that make existence viable and that generally define the subject's ordinary personality. As for the search for the second shoe to complete the pair, it translates the difficult reconciliation between intimate desires and reality and, of course, the dream also symbolizes the difficulty of finding a partner to one's foot.
Red: rage, hatred, vengeance, vitality, strength, etc.
Find: a bargain, a stroke of luck, to stop looking, etc…
Summarize:
You underestimate your potential and your reserves of vital energy. Yet you have all the means to succeed without having to rely on a man or others.
Right now, you find it hard to reconcile your desires with reality, and sometimes your rage and hatred drive you to your limits. But in the end, things always work out for you, because you eventually find the other shoe.
Best regards
Ladysally
