Hey Victor,
Glad to see a new footwear project thread started. I think I might jump back to sketching before getting too lost in rendering if I was you. I think you still have a lot to explore, and refine your project statement more clearly.
You mentioned pushing the aesthetic towards minimalism but the concept looks rather busy and fussy with the circuit board graphic. Is there a purpose for it or it is just aesthetic? I don’t think there’s anything wrong with using it as a graphic but maybe more subtle and less heavy handed.
What is the thought behind the dramatic arch in the sole? From a performance standpoint you might be causing a lot of issues.
Looking forward to seeing more
