I have had these for a few weeks now. So, technically, I'm not sure how durable they will be since I haven't put them through the wringer. So, that's why I didn't do a full 5 stars. Knowing Keen though, they will go the distance.
I got these day hikers just to demo and ostensibly haven't taken them off since. I keep finding excuses to wear them, even though I'm not hiking. So, they are a keeper. I'm stoked! My new best friends, for this summer.
These are VERY comfortable, out of the box. There is no break-in period. Because of that comfort though, these are definitely day-hikers. There isn't the stiff support most people want, while carrying a heavy backpack. If you don't like a stiff boot for backpacking and want something closer to a running shoe feel, then you will love these.
My favorite feature has to be their wide toe-box. BUT! They don't look boxy at all! Somehow they designed the top to look "normal", but you'll quickly feel that you have a lot of room for the ball of your toe to make full contact with the ground. I like to splay my toes for balance, so this is an incredible important feature to me and I like the added bonus that they still look slim.
I gave the waterproofing a few good tests, walking right through the streams. They stayed dry as dirt, so 5 stars on that front. There weren't any slippery rocks to test, since it's still early in the season. So, not sure how they will do on mossy rocks, yet.
I did take it up near-vertical sandstone rock walls, just to see how the sole performed. I'm always cautious at first, but they were golden. No worries there.
Sweat-wise, I didn’t have a problem in the high desert. I was concerned because I wore thick socks, and it was hot. But, turns out, it really wasn’t an issue. I didn’t get soggy feet or slippage or blisters. But, the desert will get much hotter, so I will definitely get thinner socks for the summer.
For size, go TRUE. My hiking boot and running shoe size is almost always 9.0. The size 9.0 in this is perfect, so go with your most normal size for active shoes and boots.
