Problem since day one.  The toe box keeps folding.  Also the boot liner consistently falls into the footbed.  I had Danner exchange them three times before Danner admitted to this product having a defect.  I tried to get a refund and was denied the opportunity by both the seller and Danner.  They offered me store credit for another pair but mentioned I would have to wait 3 months for a replacement.  I threw them away and will never be shopping this brand again.  I prefer Asolo, Redwing, or Bellville boots for duty.
