The best, longest lasting boxers I have found are from City Boxers. Made in Maine. They are custom made and a little pricey but last forever and a great selection of fabrics. https://www.cityboxers.com/
I'm always interested in well made socks - especially from the UK. I just found this company http://marko-johns.com/
Has anyone purchased these? They seem reasonable especially compared to Corgi. I ordered two pair and will give an up date when I receive them.
