For a shoe to be a stellar minimal shoe, I look for and consider the weight, flexibility, tightening system, drop (height differential from heel to toe), material, ground feel, and general fit. The Hattoris have a clever design where the areas of the sole where you are supposed to land are of a denser material than the squishier EVA foam that makes up most of the sole. My pair of Hattoris - granted I have big feet - were just shy of 4 and a half ounces according to my kitchen scale. It is a very light weight shoe with a great sole...
Just Okay
This shoe has some real positives but also some problems that keep it from being a great shoe.
Pros:
Extremely light weight
Decent flexibility
Cons:
Poor ground feel
Not wide enough for me
Durability concerns
I will probably use this shoe for 5k maybe 10k races and that is about all. The light weight makes it a great racing shoe but the poor ground feel and narrowness doesn't make it a great long distance shoe for me.

Good Shoe
The pair I wore were light, flexible and nice to wear on short runs. Anything longer than 8 miles I got blisters around the toes as the toebox was too roomy and my foot slid around. Wearing socks to take up some of the roominess didn't help. My foot is average in width. Other than that, they did well. Its nice to have a zero drop shoe from a major shoe maker like Saucony.
