I know a couple of people have made them, but I haven't (yet).
From what I remember, the "floats" or strands are quite short and so I'm not sure they would catch on too much.
If you are in any doubt, you could knit a little swatch and put it in your shoes. If you do catch it on stuff, then you haven't wasted your time knitting a pair of sock you'd never wear!
