Sketch-Fu: Men's Footwear

Hi All,
This is my first post here. I just recently turned my attention towards designing footwear and here are 20 teaser examples of my quick “upper” sketches. These are of course developed with different tools than traditional media sketches but due to the speed with which I can generate them and the loose gestural nature they end up having they are technically just “sketches.” Used as a means to stimulate new aesthetic directions I think they are pretty fun. So fun in fact that I did 700+ of them last week.
