after putting 100 odd miles in them i have to agree with Ish, they are without doubt the most comfortable shoe ive worn, very very light, very responsive,
the bump or lack of heel is very noticable at 1st but not in a bad way, perhaps since i run with a midfoot strike anyway, if you heel strike then you might have some issues transitioning to this shoe, I dont even feel it anymore when i run in them, they just feel like a minimal shoe similar to my old kinvara's. or nike free.
It's a serious shoe and i think finally sketchers (or should i say the man behind the nike free range they employed to design it) got it right on this. they have a surprising amount of cushioning whilst still giving you a lot of feedback from the road, you do feel the surface underfoot much more than regular shoes, I will say though, unless you are a 5ft3 skinny elite runner with perfect form you probably wouldnt want to use them for much more than a half marathon, they (for me at least) are very much a middle distance shoe.
They do however fall down when it comes to running steep down hills, most of the time its fine but on one of my routes there is a pretty steep drop for about 100 yards where it's almost impossible to avoid coming down on your heels, But there are few races that include such steep gradients (in fact ive only seen it before usually on a trail/off road run where you wouldnt choose these anyway) so it not likely to be a problem for most people.
the only other possible negative is grip, i 1st ran in them after rain and they dont have the same grip as my nimbus, i didnt expect them to tbh but it was pretty noticable, i'm far from a fast runner but on wet ground i found myself taking some sharp corners a little more carefully, it's not bad though, i didnt feel like i was going to slip or slide at any point, my friend who bought them too usualy runs in Nike Lunaglides and she said they are much better than the Nike's in the wet, in the dry its no problem at all, very good grip.
This is obviously not a shoe for everyone, its name will never get a great deal of support from a lot of people, but if you midfoot strike or are looking to change your form a bit, and want a very lightweight and fast shoe, give them a try, or at least dont write them off. you only need to read around the internet to see even the most critical skeptics have changed their minds on them.
