Thanks for the file, yguerrero2010.
Typically I would suggest switching off the Skin object. Then, go to the Weight tag, set the Binding Pose, and then switch on the Skin Deformer again. This will fix the “shoes”.
This works with your setup as well. However, I have no idea what you have in mind with the mesh or how you set up the rig (Adjust).
I’m used to all kinds of uses, and they go certainly from close to human “mechanics” to “surreal constructions”. I’m open to any expression or directions in art, no problem. Since you haven’t shared a lot of information, I’m not clear what your target is.
A few things that stand out:
The adjustment dots for the joints should be inside the body
An extruded object should have no polygons inside like a “cap” was left on during Extrusion, and each time unwanted inner polygons were produces.
Edges will not bend. Pretty much anything is based on points (vertices), and those get moves around with Deformers. Edges and Polygons just follow along. Legs with no vertical division will not bend.
Again, that might be all intentional. If not, some basic tutorials might be a good idea:
The three-part series from Bret Bays (You will find his name in a lot of Disney Movies, the latest to my knowledge: Raya

An excellent introduction to the Character Object from Matt Umney, who is part of the Maxon training team:

I hope this gives you some good information.
All the best
