Shoes with toes?

So, i saw a post on a blog i watch about these shoes with toes.. like toe socks but shoes for running or w/e outdoor sport you do. I looked them up and it looks like someone got some of that liquid rubber stuff from home Depot and coated a set of toe socks with it and called them shoes. Does anybody know if it would be easy to make something like these shoes for under $75?

The link below is the official site for these shoes. I have yet to find any other company that makes anything like it.

I'd be interested in them, too. People who wear them swear by them. For those that don't know, the idea is that you walk more naturally and in a way that's better for your spine/posture/joints/etc when barefoot. These provide a thin layer of protection for your feet, but offer no support. That being said, you need to mimic that effect before mimicking the product. Leather seems like a good option to attach to the bottom of a sock. If you found a material that could be melted or comes as a liquid (like a rubber), you could make a plaster mold of your feet to pour it into, and then fashion some sort of straps or sock to attach it to.
Finally, something uglier than crocs.
