Tight on my wide feet, but not intolerable honestly, I'm a 14 EEE . IF you're in a similar situation you may want to look at the Wide Open socks which are made by Darn Tough and are interchangeable through their warranty. So even though i have over a dozen of these, new, I can effectively trade them for the stretchier WO version. I really like the design and overall quality. Perfect for 6" or even 8" boots, about 8.5"-9.25" from your heel up. A little compression is OK, wish they actually made them wider. Great Quality no matter what. 👌 Go Bros seem like great people too!
