I took my Merrell Tough Gloves (with Injinji midweights) out today for about 3-4mi or 5-7km (mixed walk/run) since it's colder. It seems when I run it is fine as long as I keep momentum. The toe spring is actually more noticeable as I get slower due to less of forefoot flex and less turnover.
When I walk however, I notice I'm more midfoot but the problem for me is that after about 15 miles of wear, I notice that my first metatarsal doesn't really touch the ground due to the uneven tread. Also, it seems that the tread under the toes (where the toes split in Vibram Five Fingers) is actually more than that of the rest of the shoe to compensate for the slight toe spring. Another thing is I notice that there's more extra vertical room for my toes than I need even with socks.
If you haven't seen it, the tread is like this:

http://minimalistrunningshoes.org/wp-content/uploads/2011/01/technology-soles.jpgI'm beginning to think it wasn't meant for asphalt or concrete even though it's listed as "MEN'S BAREFOOT - LIFE" (
http://www.merrell.com/US/en/Barefoot_Collection). It makes a tapping noise if you land on forefoot on hard surfaces, probably from the forefoot "shock plate". At the end the bottom of my large toe near where it attaches to the 1st metatarsal had a redness akin to abrasion (due to pronation?).
My question is this: is it the 12mm stack height? or is it the Vibram sole that's uneven? or what? It's not horizontal room.
edit: or should I just listen to these guy(s) on Amazon who says they don't live up to barefoot:
However, it's not a match for the Vibram Five-Finger shoes in the ways that it claims for itself. It doesn't live up to its "barefoot" description. The sole is just enough thicker in the middle to effectively immobilize your toes and force you to curl them up uselessly. In fact, your foot is likely to be as stiff and platform-like in the Tough Glove as in a light-weight sneaker with minimal heel. I wouldn't consider running or hiking strenuously in this shoe. If you're ready to try out the 'barefoot' concept in footware, based on the notion that the human foot is a functional adaptation to bipedalism based on five million years of evolution, get yourself a pair of the Vibram Finger-Fingers, the model with the slightly heavier sole, and take your chances with the quizzical stares. Then consider these Tough Gloves as a compromise back-up for fancy dress occasions.
The sole is a little stiff for a 'barefoot' shoe in that it pulls your toes upward compared to the ball of your foot. This kind of makes you feel like there is actually a negative drop in the shoe from heel to toe, and limits the barefoot feel, reminding you a little that you're wearing shoes.
As for barefoot feel, etc. While it was a bit harsh on my arch when I walked on large pointy gravel, I mostly want a thinner sole with more groundfeel and flexibility. These feel like a bit much shoe to be
called barefoot. I was suprised at how thick and hard the sole was, I was expecting less. And I don't go barefoot too horribly often, and have never set foot in a five finger.
