Why Aren't My Colliders Working?

I am working on an simple AR game where the player scores points by kicking a soccer play into the goal. I have a sphere collider and ridged body on the soccer ball and box colliders on the soccer 'bot' kicker's feet. When I run the game, the player's right foot strikes through the ball, but nothing happens.

Here is slo-mo video capture of the kick. Any suggestions on what's wrong?

UPDATE: Discovered I had trigger on the collider. Turned it off and now works... sort of. Ball not reacting to kick impact as I want. What is proper Physics Material setting for human body (soccer shoe) and ball: Bouncy? Rubber?

 

Here is new under current settings.
