You're a sock without hands so you're very limited to what you can actually use. As a sock, you have an opening in the sock which can be used to generate force to throw out a dagger or darts.

Your Constitution score increases by 2.

Socks can live forever if they're kept mended and up to par. They do not age, but would consider their "birth" to be when the sock was made even prior to being sentient. It may or may not remember when it was created.

Most socks are just neutral. They were socks in the beginning and still are socks. They don't usually tend to have strong pulls toward anything unless the being or the magic that made them sentient had a strong pull toward any alignment.

Socks are tiny-small, tending toward the tiny size. How big is your foot? That's the size of a sock. It can be any foot size, however. If you happen to be a giant's sock, then you might be up to 3 feet long. Who knows? 

Your base walking speed is 5 feet. You probably need someone in your party to carry you around, but you can inch your way around like an inch worm.

Since socks don't have eyes, you can rely on your blindsight to perceive your surroundings.

You have advantage on saving throws against poison, and you have resistance against poison damage (explained in the “Combat” section).

You gain proficiency with the weaver's tools, alchemist's supplies, and the brewer's supplies. Socks gotta do something right?

You as a sock, were imbued with some sort of magic. You automatically get the Arcana proficiency and as a sock, who notices socks? You're stealthy due to your tiny size, making you harder to hit and people don't notice socks lying about. You are proficient in Stealth.

You're a sock. You don't need to eat. Just make sure you stay intact! Find a nice wizard to do a mending spell on you every once in a while maybe. That should help make you brand new.

You can speak, read, and write Common and Undercommon.
