These are not the "New" version, which costs several dollars more and $5.95 shipping from another distributor.  The new ones have a hand grip at the back.  These have nothing more than a string at the back, which I found makes them difficult to pull out of my shoes when they are in snuggly.  I also noticed that there is a size chart on the new version, but no description on this version.  The small is for shoe sizes 6 - 7 1/2, for those of you who would like to know.
