Men's Multi-Pack Mesh Ventilating Comfort Fit Performance Quarter Socks (6, Grey (12 Pairs), Shoe Size: 8-12

Are these sesmless?

Is there odor control?

Love these socks but why don’t they make mid-crew size?

Are these on the thick end or thin end of performance socks? I have some space in the back of my shoe that I think I need a thick sock to fill.
