I dig the concept but am not so sure about how all the colors work together. Could we try using two-tone instead of 3? Any chance we could somehow throw a shoe-lace end on the end of "salvaged", you know the little plastic pieces?
#53 #54 #55 - These designs seem a little too blocky and bold. I envision something with finer lines and lighter colors. Can we also try throwing the name on the bottom? Do you have any experience with a more "sketch" like design, as if it were drawn with a pencil/pen?
Regarding the new shoes, with red/white/blue I think the colors seem to be clashing more than I expected and take away from the quality of the outline, making them look a little choppy.
