So I've worn these for a few hours around the house today and just returned from a quick 5k run around my neighborhood. Mind you, I can do the same 5k run completely barefoot comfortably.
Overall, I like the feel, but I'm looking at two problems:

1. There's a ridge on the bottom of the shoe's forefoot (marked with yellow arrows in my picture). This ridge shouldn't be there- I can feel it with every footstrike as I roll through towards my toes. It feels like I'm stepping on a hard edge of some sort with every stride. Way too much of a pressure point for me to be able to count on these shoes to be comfortable at any significant distance. I can see it's part of the design idea- placing thicker rubber under the forefoot- but the edge of that thicker part falls right under the bones in my forefoot.
2. The red arrow shows the location of a pretty hefty seam on the instep of the shoe…big enough that I don't trust it at all. If I can subtly feel it there on a 5k, it'll be a massive blister by 25k. Socks would remedy this…but, in my opinion, that completely negates the point of these shoes. No good, not what I'm looking for.
If this is supposed to be getting me closer to "barefoot" but I'm feeling seams and ridges and might have to wear socks…well, that's not working too well with the "barefoot" idea for me.
I really don't understand why every shoemaker on earth seems to find it critical to put gimmickry, weird seams, ridges, swooshes, and other nonsense on their shoes.
Other than this, I actually like them. They feel good, have great flexibility, feel pretty natural- just enough armor to not worry about puncture wounds. I just don't think they fit my feet well, not to mention I'll likely be able to run faster in flats due to more toe protection (not worrying as much about foot placement- which wears you down mentally).
I'll be returning them tomorrow and sticking with my MT100s.
I am pretty interested in trying something from Feelmax- basically they're synthetic moccasins with very little apparent gimmickry on the soles.
I'm kinda bummed though, I wanted the KSOs to work for me.
