I just got a new pair of Earth Logan-K today. I haven't seen Earth mentioned on the forums for sometime, and besides that... I just have to write and tell you all how great the microfiber feels.
When you first pick up the shoe box the first thing that crosses your mind is that maybe there was a mistake and you got an empty shoe box; that is how light their casual shoes are (I think this probably applies to all of their casual, and activity shoes). The Logan-K style is basically Earth's unisex laceless shoe. The same style as the Sketchers I've been wearing for the last 10 years, in fact. It pains me to say, after looking hard for a shoe that matches my old shoes so closely, that the Logan-K's have been discontinued.
The fit of these is so true that they fit like a glove, while that may not initially sound like a good thing, they are actually the most comfortable shoe I've worn in a very long time, and without a doubt THE most comfortable new shoe I've put on straight of the box. They don't have the new shoe awkward feel. They feel like a nice pair of shoes that you have "broken in" over some time. Between the breathability of the microfiber and the lightness of the shoe, it's pretty easy to forget that you're wearing shoes! Also I have no issue with the negative heel, it actually feels quite natural to me.
Few shoes in my eyes are worth their price tags, but like with anything sometimes you find a gem. I would certainly recommend checking Earth out if you are looking to splurge on some decent vegan certified shoes.
