The Original Blue is Back!
I discovered the Original blue insert decades ago.  Have some of my original purchase.  Could not believe it when they changed them to white and purple.  Only difference I could see was that they made the heel thicker, which takes up more room in your shoe.  (I half-size up for boots so the inserts fit; was not a problem with the Original blue.)  I searched everywhere for the Original blue, to no avail.  I loved the arch support so much I purchased the white/purple in 2010 from Amazon.  I just now found the Original blue on Amazon by accident.  What luck!  What fortune!  What kismet!  I bought the two pack of the Original blue for $15.99 and a three pack of the white/purple for $16.36, discounted from $21.99.  Thank you ProFoot and thank you Amazon.  I always shop first on Amazon.  I don't mind if Amazon takes over the world's shopping venues.  The deal, the convenience, the bargain, the selection is always in my favor.
