I'm sorry, I don't know the size. I used watch kids and they were given to me. I measured them and here are the dimensions: Toe to Heel: 2.5" Heel to Top: 2" Cuff Width: 2" As far shipping by Christmas, posting this late was my bad. I will ship Priority so, I believe so but, barely. I will mail tomorrow morning but, even at that, I believe it will be Monday or Tuesday before they arrive. Sorry, since my kids have grown and are now gone, I lost track of how close Christmas actually is. I apologize.
