In the early 90's when I was at CCPM someone came to us to test some silicon filled devices (no channels). I found them unstable. For example when you push off on your right foot, moving laterally to your left, you will tend to put more weight on the outside of your foot and this will squish all of the viscous fluid to the medial side that will tend to invert you. For my foot, it was better than no orthosis, but not as good as my rigid orthoses.

The department chairman described the feeling as stepping into a cow pie.

have seen some prototypes a few years ago of one filled with a cork & ceramic clay paste with channels in them, as the foot warmed up the clay it becomes softer and more malleable

from what i remember they had some base shape to them too in terms of a heel cup and basic arch shape, the flow material moved between the arch and the forefoot

With a strategic channel design and filled with a non-Newtonian fluid the concept might become interesting.

For a personal Thank you - The Cow Pie made my day, you should recommend that to be their sale slogan!

Can you explain what you mean by this?

Surely you could cheat and add a valve system within the compartments. This valve could be pressure operated allowing movement with pressure to be more gradual then when the foot is in swing phase it resets.

The liquid perhaps should be substituted for a quasi-solid like toothpaste. Combine both could again as a more gentle resistance to the forces. Without the spring effect aforementioned in the Cow Pie post.
