This is the first time I have purchased hiking boots online. I hike a lot. 40+ miles per week generally. I wear out hiking boots in about four months, and am getting tired of driving all over the place trying to find something that fits, and isn't too expensive. These are great! Comfortable right out of the box. Sturdy but still flexible enough to move with your foot. I have only just started with them - but at this price, and with the Amazon Prive fast and free shipping: I will be coming back here for more when I wear the treads off of these in a couple hundred miles.
Positive
