Subject: RE: kinvara 2 vs. kinvara 3 Amigo, I've used both, and I'm trying to transition into the K3. They will feel amazing if you put them on. In fact its fantastic. There are plenty of differences between the two but the main things I have noticed it that the toe box is wider and that the flex-film? is a new thing for them. I thought that since the toe box would be wider that my foot would slip, that was countered by the flex film. The film seems to respond to any tightness in the laces and is able to counter the wider toe box. That's a major bonus if it is a concern. The heel cup was a little higher than the K2 so I suggest you use some lube on the back of your Achilles as they will probably give you blisters. But then again I dont wear socks. the ride is great, if your a neutral runner. I did find that I felt more of the arc support more when I ran. Especially more than the K2. The feeling was similar to the KSWISS Blade light but I assume they designed that to support your foot later in a marathon. Overall it's an amazing shoe and if you're a fan of the K2 the switch should be easy!! cheers! |
