I have only used these a handful of times but so far I am very impressed. They are a little bit wider, as most Keens are. But they run true to size and don't need much time to break in which is awesome. They seem to be super durable so far but only time will tell when speaking to the durability of an item. I haven't worn them when its super hot out but they seem to be pretty breathable as well which will be nice once the Utah heat is in full effect this summer. They are waterproof and will be awesome on those days when the rain has caused some mud on the trail. Another cool feature on these boots that I am stoked about is the mesh lining. A lot of boots can be super hot and my feet tend to sweat more than the average human. This sweat wicking mesh lining should help with this and provide more comfort. Keen has always been a reliable brand that makes great product day in and day out, these are no different here. They come in multiple different cool color variations and I think you will be very pleased if you decide to purchase these boots.
