I very much dislike jeggings. First of all, the name is awful. Second, they market them to fatties (like myself) and that is just the worst idea ever. We should not be allowed to wear anything like skinny jeans, so few of us look good in them at all. I know that I would look like 10 lbs of sausage in a 5 lb sausage casing in even the best-fitting jeggnigs.
That said, Andy, you look great in them. I think having them cuffed might make you look a little short, but who cares? You and I are the same height, and I know it's hard to make myself look noticeably short to others, because I tower over half the people I know.
If they are comfortable to the person wearing them, awesome. Go for it. There are worse fashion faux pas to worry about. For example - women who wear shirts with empire waists, or similar, with the line going across the boobs instead of under them. What the hell? How do you not notice this?
