Looks like a sock for fancy dress parties !
But actually, it is a Strassburg Sock to cure Plantar Fasciitis (heel pain). The Sock bends the toes, and you are to wear the sock to sleep every night. In about a month, it should cure the Plantar Fasciitis. See the "Prolog of prolog" section of my account on this matter in:

Why does bending the toes has anything to do with heel Pain? It is a mystery to me. The web site for the Sock is: http://thesock.com/
May be you can read it and tell me the reason.
