I think they should improve the foot model altogether. They hardly even look human. With such a big part of this game being the details in customization, the fact that the feet are looking the way they do and not getting the attention they deserve is representative of how ideas and tasks can get pushed back and forgotten in a game of this size. Therefore, I think it's up to the community at times to remind the devs that certain things deserve their attention. I highly doubt that having to walk around on tip toes everywhere was supposed to be a permanent feature. They probably set it on the back burner as things needed to get fleshed out, balanced, and bugs needed to get fixed. They probably eventually settled and decided that it was going to be too much work to get the feet to work realistically.
