On one of the shoes there is a weird lump under one side of the ball of the shoe.  I had put that shoe on first so I thought maybe it was some ergo feature, but its not there on the other shoe. Its just a poorly made shoe.  But even without the lump, I don't think the foot bed is very comfortable.  If you are accustomed to wearing Teva... these aren't even close to Teva comfort.  These are definitely going back.
