I only wear comfortable shoes I like to look at. Some of my favorite shoes going back 10 years would be Puma H Street leathers, Adidas Crazy Explosive, Altra Escalante. All light, comfortable, attractive shoes. One would think these type of shoes would prepare me for the Terrex Agravic Tech Pros (modern materials and look), but the Agravic are unique. First of all they have an inner that secures around the foot with the boa system. There's an outer sleeve that zips up around the ankle for added support. I call the shoe lightweight, but they are heavier than I'd expect when holding in hand. There's very real structure/firmness to the sole, but I wouldn't call the upper that protective. There's nothing convenient, or easy about these shoes. You kinda have to fight them to get them on (sure this improves with wear and time), but once everything is in place, they snug up to my foot very nicely. My foot is a mens American 10, and the 10 fits perfectly - I know this too because I always use an after market insole, and it (the after market insole) is exactly the same size as the removable insole included with these shoes (from heal to toe). What is weird is my foot kinda moves around in this shoe in a way that would be alarming in other shoes - but? There's nothing to rub on like in any other shoe. If there is any issue on the trail with hot spots, I'll re-visit review. I think these shoes really are specific in their purpose and usefulness. They don't have the structure or protective nature of legit hiking boots like my current favorite the Arcterix Acrux TR GTX, but they offer more support than the average low top trail running shoe. They may not be water proof, but certainly protect from the environment, and while running/hiking could be worn at lower temperatures. They should be very good spring and fall activity shoes. The sole appears very sticky, functional, and they are very comfortable with the cushion.With the Boa, I recommend really cranking them down, then release, move foot a little (to get just a tiny amount of slack in the boa lines) then snap back shut for best comfort fit.fully admit this review springs from a very positive first impression. after extended wear, if there is any issue, I'll revisit this review.
