I tried them on today, although I didn't run in them. From what I felt and what I've read, these aren't a minimalist shoe really. They're super light and they have a smaller heel-to-toe drop than most trainers, but they're stiff and you don't get much ground feel. I had a Kinvara on one foot and a Grid A4 on the other and the difference was very stark (the Grid A4 being much more flexy with better feel and even lighter).
From what I've read, they will allow you to heel strike, but they won't force it, so if you're looking to try mid/forefoot striking, it's an option with a fallback. They really seem like a middleground between minimalist and, er, not minimalist. If I was choosing between regular trainers and these, I'd definitely give these a try.
I just did a short (2.5 mile) run in them. I am still getting over a head cold (so I'm stuffed up and have been coughing), so I'm not ready to say one way or the other how I feel about them with certainty. I am coming from the Nike Vamero line, so it's definitely a different type of shoe than I have been running in.
The store I got them from let me bring them home, and if after a day or two of wearing them on runs (treadmill/grass only though) I don't like them I can return them for another pair. So todays run was on grass only. My impressions:
First impressions were that they were very comfortable, and hugged my foot well. Walking around and doing warmup jogs in my yard they felt good. I could feel the ground a bit more than my Vamero's. They seemed to be a good shoe to transition to a more minimalist shoe in the future.
During the run, my right foot really began to bother me both on the inside (innermost part of the arch) and on the outer side. I have had some issues with these in the past, but these shoes seemed to not help. I'm not sure if it's just because they are using muscles/tendons that aren't normally used or what. In reviews I have seen, this is one of the common things I see negative about the shoe (the lack of support for the sides of the foot). This, being sick, and wanting to keep the shoes in good condition in case of a return all were reasons for the short run. I could feel more of the ground than my Vamero's during the run as well, so while they might not be true "minimalist" they are definitely not the normal shoe and fall somewhere in the middle.
It's been about 30 min since I got done, and my feet are definitely sore. This is to be expected to a point with a new shoe, especially one that isn't the same style of shoe as what you're coming from. For me, the Kinvara's are one of the most extreme cases of this happening. I don't want to blame the shoe though, since I've never really run in anything other than thick soled shoes with a 8mm+ drop (well not since soccer anyways).
I'm going to give them another run on Monday after class at the rec center at school and see if I get the same results. If I do, I'm going to be returning them for a different shoe I think. I would really hate to do that though
