Skidders Indoor/Outdoor Socks

WHY DON'T THEY MAKE THESE FOR ADULTS?

I'd love to wear my socks all day, indoors and out.  Don't need shoes or socks with these combo Skidders.  The comfort of a sock but with the protection and traction of a shoe sole.  And there's nothing boring about these bright, colorful, cute shocks.  And it's much easier for tots to learn how to walk without the clumsiness of foreign, bulky shoes.  Promote the healthy development of growing feet.  Machine washable.
