Strange distorsion when walking

[IMTEODNK]

Hello Ch users !

Could you help me concerning my problem of rigging ?

When my puppet is walking fix points seems to appear creating distortions i don't understand what i missed..

My .ai file is based on Kaufman puppet

Thanks for your help !

Are the leg groups independent (crowned)? Here is an example of the rigging for Walkbot.

Hello Jerry,

Thanks for your answer.
I made a screenshot of the puppet for more clarity
