FEYHAY Copper Compression Socks (8 Pairs) 15-20 mmHg Circulation is Best Athletic & Daily for Men & Women, Running, Climbing

What size do I order for 9/1/2 shoe size?

Are the hard to pull on like regular compression socks?

Are they uniform in size from pair to pair? i have tried other sellers and find while the package says l/xl they are not uniform. some pairs are s/m.
