Hello and sorry for the late reply!
The typical way to have objects follow a path is to first create multiple separate bones in the Spine editor that follow the path - you can have a look at the tank-pro
or stretchyman-pro
example projects that come with Spine.
In Unity you can then create a child GameObject at your character and attach a BoneFollower component that will then follow one of your bones (which are constrained to the path). You can have a look at the Spine Examples/Other Examples/Sprite Shaders
example scene, here Stretchyman comes with eight bones per leg, where you could now create a child GameObject with a BoneFollower component that follows the bone back leg 4
