It just seems to me that such small grooves, being so thin, would wear away quickly. I use the K-Swiss Ariake and have never felt a better grip from a shoe. I'm sure you re familiar with the flat fore-sole (if I can call it that) with grooves to repel water. However, I have never worn them when it has rained, or used them on very wet surfaces, so I can not attest to the worth of such groves.
But, I feel that the sole you have right now, with or without grooves will be great. If the grooves wear away, then you are left with a dozen or so squares of flat material which will still work well.
An idea, though. Having a sole with "back-ups." The sole should be designed with 3 layers. First layer, the grooves. Second layer, the squares. Third layer, a flat surface under the squares. Now, these layers in a regular shoe would already be produced. BUT, they would not be produced to TAKE OVER, should the other layers wear away. For instance, if the tread on a running shoe wear away, you are left with a worthless running shoe.
So, the third layer of the Carapace should be designed to take over for the other layers (grooves/squares) should they wear away, instead of just being there for the squares to be attached to. This creates a longer lasting sole.
Just a thought.
