Fit perfect and true to size. Comfortable right out of the box. I have had 6 pairs of Keen boots, all great, but these were the most comfortable without any breaking in. I wear hikers daily, but also do a fair amount of hiking, hill walking and backpacking. Not detailed in the description, but the third set of lace hooks from the top lock allowing you to tighten up in the ankle and loosen up the foot laces - or vice versa. Been waiting for something with more support than a day hiker from Keen, and these fit my preference perfectly.
