Replying to Ski socks, in between sizes. Options?

So a while ago I posted my issues with darntough never quite fitting right, I was met with praise for the company and I never quite got it. They're great but don't fit me well. They're not that elastic but that may only be part of the issue. Turns out, I'm right between sizes. The L is a little too tight and the XL a little too long, I have both. Large is sized like 9-12 and xl is like 12.5-15.

Anyone with similar sized feet (12.5) find a good pair that fit and isn't between sizes? The XL work ok but before I drop near 30 bucks on a pair it'd be nice to have ones that fit better. I'm either stepping on the heel pocket or it bunches up behind my heel. Thanks in advance!
