One of my favorite so far. Ranks up there with the Asics Novablast but maybe a little bouncier which is a good thing to me. I used to always run in Pegasus, but then I was having problems with the heal counters messing with my achiles. The Invincible puts no stress at all on my Achilles, and is still a pretty fast shoe for a mid-striker like me. Even with the high level of cushioning, it feels stable and isn't as sloppy as the Asics Nimbus was for me. For reference, I have a high-arch foot that is probably on the narrow side, weigh 185 and 6'1. I've always worn a size 12 Nike and do with these as well. When I'm running slowly I'm a heel striker which feels very good in these, but when I pick up speed I'm more of a mid-striker which also feels good but not quite the same level of bounciness. I usually use them for 3 to 6 mile runs.

Love the shoes feels like walking on a cloud. Wants to purchase another pair. Just love love love the shoes.

I liked the shape of the shoes and it worked well for my running, however the product seemed to have a problem in quality. The bonding doesn't last long.
