>General Running>Drills to correct splayed feet running form
Yeah, I guess "fixing" it will depend on whether or not you've identified the "problem" that causes the imperfection. If you engage your hip muscles to straighten the leg, well you are developing them to hold the leg in the right position. But maybe you are just wasting energy fighting the original thing that caused the form imperfection. Who's to say? Surely not some schmuck on the internet. But I think that solving the problem will probably take more work than just holding the leg in the "right" position.
