Question How to sync animation speed with movement speed?

So I downloaded a bear model from the assetstore with premade animations.
I use the walk animation when the bear moves forward.
However if the movement speed is to fast it looks like he is sliding.

So my question is:
Do you just try out different animation speeds and movement speeds unitl it looks smove. So trial and error...
or do is the way to make this work without having to tweek values again and again until it looks right?

 

Perhaps you could measure the length of one step, and use that distance to figure out how fast the clip should be played at different speeds?

 

Flag a bool in the animator.
