What cycling socks fit a 43.5 foot like a glove?

Paceliners! What socks fit a 43.5 foot like a glove?

Very odd question, I know. But with cycling socks being so damn expensive, I'd like to know what brands to look at before spending so much money for a few pairs of socks! The SockGuy socks I have don't fit right at all. Medium is far too short, and large is far too big. The heel seem is all the way up to my Achilles, whereas with the mediums it seems my toes end up getting crunched because the heel seem is way too far forward. I don't have any other different brands, but looking at the size guides, it seems the cut for medium/large is size 43 or 44. This indicates I'll have the same problem!

I'm really only looking at summer socks with a 6" ride. A little more/a little less is fine, but 6" seems to be the sweet spot for me.

Any and all advice is welcomed!

Swiftwick is my preferred brand. Excellent quality.
Just the right amount of padding, compression, and fit.

I'm a 43.5 wide.
Defeet, Swiftwick, Sugoi work for me.
I think Amazon has Swiftwick so you could always return.
