These were a custom order for someone and have already been sent out, so I cant have someone model them . I do have a few other pairs modeled on my etsy page though.
If you end up wanting to make some yourself I can tell you how I make mine. I believe that Kwik has a pattern for adult footies as well.
For the feet bottoms I used a fabric called Jiffy Grip. Which works out pretty well. I also like the way it looks with the little bumps.
