As always, thanks for the input guys!
The shoe was definitely designed with durability in mind. Obviously, yes, it needs testing to all be substantiated, but the best rubbers would be used. The whole idea was to create a cheap, recycleable shell that you can replace for 30-40 bucks while keeping the sock and mixing and matching colors. The molded footwear is cheap because there is no labor involved with stitching in linings, foams, counters etc. But it also works perfectly here because it stretches to form to the foot, has no seams to rip or wear, and lasts a long time!
Again, as stated, the split toe was to bring the foot closer to it's natural state and increase balance as well as the ability to grip link fences, ropes and crevices.
Thanks again to all! I am about in the middle of finishing this shoe, so I will update in the future as well as getting input on the less advanced models.
