How do Darn Tough fit cankles?

I'm looking to buy a pair of these for myself to try, and a pair for a loved one. For lack of a more diplomatic way to phrase it, they have cankles. We both wear the Kirkland crew socks daily now. I've worn Kirkland's merino wool socks and found them very comfortable but too warm most of the year. They wear a size 12 women/10 men. I'm size 12 men. Any recommendations on sizes/fits?
