question about 6 configurations of SignWriting

[Claudia S. Bianchini]

Hello
I'm Claudia Savina Bianchini and I'm a PhD student at ISTC-CNR (in the team created by +Elena Pizzuto+), in Rome.
I'm doing a research on SignWriting and I've a question about some SW configurations.
There are 6 strange configurations (where there is a deficit of possible orientation) and in those 6 I really can't understand how I've to put my fingers...
Is there someone that can explain them to me?
The configurations are (from ISWA-2008):

My problem (for glyphes from 1 to 7) is that I've searched everywhere but I can't find a translation for "heel" that has nothing to do with feet. So my question is: is there feet's configuration on SW? and, if yes... why? I've never seen any deaf making configurations with their feet!
And I really can't understand the explanation for glyphe 8.

Maybe all this problem is caused by my horrible English?!?!

Thanks a lot to all
