If the Penance Hall site was more detailed I would have ordered. But there are no product descriptions.Here is another company people talk about. Pretty expensive, and very odd in that the selection is very limited, but said to be very good.
That said, these are some of my favourites, the one colour textured silk/wool Viccels here. The best of all their socks imo. Numerous great colours to choose from. Unlike many Vicels, they are a good length, not too tight on of calf, and stay up.
The second best socks Viccel make are the herringbone silk/wool ones. Not as well fitted...made for Fred Flinstone ankles, but still nice to wear.
Viccel can make very good socks when they put their mind to it, but their hand linked toes are not as refined as the better brands. They are getting better and better.
