So I've had many Keen shoes before and I have always been happy with them. These are no exception. The are very comfortable out of the box. As with any new boot, it's about 2-3 days before it's what most refer to as &#34;broken in&#34;. The first day the padding around my Achilles tendon was tight and put pressure on my foot, even with the laces loose. However after the first full day of wearing them it went away. I am on my feet and walking 12-16 hours a day and these make it seem easy.<br />The one thing I noticed with these boots is that they are HOT! I don't mind this.  However, I have had many boots before and the only ones that I remember being this hot were the Lowa GTX gortex boot (which is an extremely comfortable boot by the way). I hope that these last at least 3 years. My last pair of keens lasted at least that long, and I'm not easy on shoes.
