Blocking (socks) and odd shaped knits

I'm on the quest for the perfect sock, and as an 'improving' knitter am trying to increase my skill level somewhat. I have knitted a fairly basic pair of socks with a heel stitch heel for reinforcement, and I'm on my second pair at the moment with reinforced toes as well (shaped offset to hopefully suit my square feet a bit better).
My question is about blocking and whether it is important for socks and what it does. I understand that the idea is you dampen the knitted object and then stretch it out to size as it dries. Socks are a bit fiddly and odd shaped. I have seen some wooden mitten forms to block mittens, but what should I use to block socks? I'm wondering whether to pin them to our spare bed mattress, but worry that will make it soggy. Silly idea, could I just put them on damp and let them dry on my feet? Won't they lose their shape as soon as they come to be washed again - what does blocking actually do?

The only knitted item that I ever block are shawls where the edges curl up if not blocked.

I know that cardigans, jumpers etc ought to be blocked before sewing the seams but have found that if I press lightly with a steam iron, the rolled edges usually flatten sufficiently to make a straight edge.

I have only ever knitted gloves that could be considered as odd shaped items and made those on the round using 4 needles and didn't bother blocking them.

Blocking a garment would ensure that the shape is correct if giving it as a gift but I wouldn't bother if it was for myself.

Damp socks would not be very comfortable and they would mold to your foot's shape once they have been put on so personally wouldn't bother.

I think most of the sock knitters around here use something like this: https://www.amazon.com/SEWACC-Blockers-Stocking-Stretchers-Template/dp/B09L5MPFYQ/ref=sr_1_15

But, this one is pretty fancy. I know I've seen both less expensive and more...
