Comments: just got the shoe ran 17 miles in them so far and already showing sligh signs of tearing underneath the logo on the outside of the shoe. I love the feel of the shoe but If the tearing becomes a problem any time within the next 100 miles ill be pretty disappointed.

Comments: I have used 2 different pairs of this shoe and both have shown tearing on the lateral side under the logo. Not happy as they each have only had 50 miles on them. I like the ride and feel but wish the upper was more like the A5. Sometimes you win and sometimes you loose. I lost.
Comments: Nice light show with decent cushion. Runs a bit small, but 1 full size up fit me well. The open knit upper is more flexible and forgiving than the fine nylon on my Kinvara 2s. The Fastwitch feels less cramped and restricted. The Kinvaras ripped after only about 100 miles right at the flex point behind the toe. I don't expect this problem with the open weave on the Fastwitches. I will be using this for non-trail training and racing. I am a mild pronator when standing/walking but running I become more neutral. My feet still feel good in these after 7-8 mile runs.

Comments: Really nice tempo and marathon shoe. Pops off the ground quite nicely with an equally firm, responsive and flexible feeling. Better fit, too, than predecessor; Fastwitch 5. Flex film contributes to an airy, more breathable and lighter upper. I sized up 1/2 size.
