well the way I did the shins was originally by the 3D model from the beta. But knowing how hard it is to get these on I extended the face just above the top of your foot so that it could be sanded/cut back if necessary without looking off all that much.
If you look here, it's been cut back considerably in order to get my foot through, but it still looks pretty good.
i'll put up a couple close ups in my next post in a lil bit. deal?
