Walkcycles are something all animators are going to do in their career. Many animators download a rig to just
animate walks.... I am not surprised many fail. There are so many things to deal with and walks are hard.
That's why you have to have the basics inside before dealing with them. I recommend reading through
this book ( The Animator's Survival Kit)

You can download all the views below. Thanks to Miguel González Viñé for creating a good rig like this one:)
