Socks too Big

I have 2 pairs of socks that I knit and are too big. I realize now that I need to go down a needle size even after a guage. Question is, how can I shrink them They are wool. Thanks in advance:knitting:

you can’t…if you try to shrink them in the washing machine they will just felt.
I suppose you could use them for decorations at Christmas time if you choose to do that!

There’s no reason you couldn’t felt them just slightly smaller (not too small!) as long as they are not superwash.
