Customize Fusion model to foot shape using parameter table and sketch
Basic size adjustments respond quite well within a few sizes (will tighten up next version_ but major changes to the footprint can create issues downstream.

Cut and sew textile uppers from available materials
There are so many choices out there, you can basically get creative and develop your own design using this template as a guideline. Adjusting the template to your own footprint (as adjusted in step 3) could take some trial and error.
