Like Tobus, I don't have a lot of length left to do anything other than have just the fringe, or perhaps a touch more, below the cuff. Even if I did I don't think I would wear them any differently. Having long tails flopping along sounds like more of an attention getter than I would want.

In regards to customizing the length, although I will defer to those who have actual experience, it may be easier to cut a piece out of the middle and sew them back together at the right length (never seen) then to mess with the fringe end. Just a thought.

Oh, and I would love to hear the controversy about the hunting socks Jock! We've about beaten the life out of the others you mentioned!!
