It seems you are suffering from a fetish; it is not healthy; socks are not the things we should smell or relish or attach to reverently.

Islam teaches us to be clean and tidy and shun that which is unseemly and undesirable. Therefore, I urge you to seek treatmenet for for this condition. You can speak to your doctor; he may refer you to  a counselor or therapist to help you.

I pray to Allah to help you overcome this fetish.
