Adidas vector shoe

This is a non existing shoe, I was trying to render a shoe without using Photoshop and try to learn to use the gradient better. The idea of this shoe is to have 5 velcro fasteners, 3 black ones going to the outside of the shoe and 2 red going to the inside of the shoe. Just trying to get the looks of shoes with velcro to look better. Here below you can see how its made up with vector lines.
