I bought a pair of Pronghorns in December 2016, never wore them until October 2017. By end of November 2017 the stitching was failing and they were ripped. They were under warranty for a year, however, I didn't have the receipt or proof of purchase anymore. I was still able to get them exchanged for a new pair! I had heard from several that Danner has fantastic customer service, and after my first interaction I would agree. I was extremely disappointed that a pair of $200 boots would fall apart after about 7 weeks of wearing them, but hopefully this next pair lasts longer.
