The point of these shoes is that they are near impossible to heel strike in. There is built-up material in the middle of the midsole, creating an intially uncomfortable "hump" feeling on your feet if you were to stand or walk in them. The feeling disappears around mile 2 of your run and they are great after that. The hump coupled with the severely undercut heel pretty forces a midfoot/forefoot strike. I actually moderately forefoot strike rather than midfoot strike in these. The sad thing is that as comfortable as the uppers are on these, I've gotten blisters on the instep runnin sockless even after going up half a size to relieve the issue. The problem comes from the outer stitching that ends up rubbing on the instep. I tried sockless several times and always blister exactly around mile 2. Wearing thin socks completely eliminated the problem, but then you get less ground feel. If you never go sockless, it won't be an issue and will feel quite comfy.

Cons:
Likely blistering if running sockless (Pete Larson from RunBlogger also reported this)
Awkward when walking. I would not describe it as painful by any means, as I walk in them just fine after my runs. They're just weird, due to the middle hump.
Rear heel counter lip is a little low. Sometimes they feel like my feet are on the verge of slipping out.
Laces are ridiculously short.

Pros:
Yes, you will definitely not heel strike in these. If you do, stop running, you will hurt yourself.
Very nice balance of soft cushioning to groundfeel ratio.
Very light. As light as most racers.
Very flexible. You can just about ball these up in your hand.

Overall if you are a beginning runner on the verge of becoming an intermediate runner, I would highly suggest these. If you are an intermediate runner, I would say check these out if you are looking to solidify your midfoot gait. If you are advanced, you probably have read enough about these to not need me to suggest anything. It is the fact that I can't really say these shoes are for EVERYONE (I would say they are very good [not great] for 75% of serious runners) that I took away one star.
