NavAgents avoiding each other and using root motion aniamtion

I want to create a crowd of randomly walking people.
Navagent with speed=0.8-1, angularspeed=120, obstacle radius =0.2 works almost fine
i.e navagents are avoiding each other successfully. But animation doesn't look good - characters are sliding (like michel jackson ) . it's not possible to adjust the speed to make it look right
I can lower speed to 0.05-0.1 and apply root motion. Animations wil be ok, but navagents can't avoid each other.
There're some scripts with the same idea :

but the problem is the same - with all those tricks animations will not be good. Is there any way to apply root motion correctly ?
