This is the most comfortable shoe I've ever worn. It is very sturdy, offering protection for my foot and support for my ankle, while being wonderfully lightweight. Thanks for Backcountry.com's amazing return policy I ordered this shoe in a 7.5 and 8 and Salomon Exit Aero 2 Hiking Shoe in an 8. Many Solomon reviews have said order a size/half-size down, I completely agree. I didn't even try on the Exit Aero 2 because just looking at it in the box I didn't like the way the toe area was shaped. (Which is why I was drawn to trail runners in the first place, but because of the return policy I decided to go for some hiking shoes just in case.)
These shoes didn't need to be broken in, but I wore them everyday for a week before my trip. These shoes were first tested at Yosemite on the Mist Trail (to the top of Vernal Falls) on very steep, wet, steps and steep dirt paths. The shoes provided great traction and breathed well to keep my feet from getting soaked while stopping for numerous photos on the wettest part of the trail.
Two weeks later I was in a completely different environment hiking through Arches National Park. In the 100 degree heat and sand these shoes breathed well to keep my feet from getting too hot and the traction was amazing for crawling up and down smooth rocks. Hiking though sand was incredibly though, especially in the heat and sun, but these light weight shoes helped out a lot. My only complaint is towards the end of my hike on the they're-not-kidding Primitive Loop from Devil's Garden, I was collecting a lot of sand in my shoe. I read that the Gore-Tex version prevents sand and little rocks from entering your shoe, but living in Southern Nevada I cared more about breathability. I ended up stopping twice in a mile to pour sand out of my shoe, but I think that was because I was too tired and just shuffled my feet though the sand at the end.
Long winded review, but I hope It encourages others to purchase this shoe. Thank you Backcountry!
