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, recyclable shell that you can replace for 30-40 bucks while keeping the sock (which would be washable) and mixing and matching colors etc. 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/agility as well as the ability to grip link fences, ropes and crevices. it may not be for everyone, but again this is for the extreme trainer and the other 2 models will have more cushioning, more support, and no split toe. I was finding it impossible to please everybody with one design!
I don't think the fit of the toe would be an issue. The material expands well and should conform snugly to most feet.
The strap is designed to simply keep the shoe on your foot. It does tighten a little, but these would really have the feel of wearing socks more than tightly laced shoes. Again, maybe not for everyone.
For flexibility, the outsole does feature the articulation of Nike free for that exact reason. It will be a staple across the line with a more durable application

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.
Sam- you're right. I thought the neoprene pad over the malleolus(ankle bone) might be a nice secure feel in harsh environments, but I think there could easily be socks of different materials and heights for different preferences. I will implement that for sure!
