I see the thread’s been slow the last couple of months, but I’ve worn Danner’s for 25+ years and rely on them daily for comfort and durability. I wear 11EEEE Acadias that don’t show up online. Give them a call, or have your boot store call them, and they might have wider sizes than normally advertised.
Also, I highly recommend Danner’s boot recrafting service. Not the cheapest way to get resoled, but they’ll fix other issues while they're at it and you’ll get a near-new pair of boots back - already broken in!
