Recommendaton for walking socks for those with a high instep?

[Punt]

I'm after some good quality, mid-weight walking socks, preferably merino wool. I have a high instep, and most specialist/sports socks tend to be too tight around the top of my ankle.

Heard great things about Darn Tough socks but even their biggest size are too tight for me.

Any recommendations?

Cheers
