Best way to show footwear in a portfolio

I guess I am very lost as to what should be included in my portfolio, its possible I am having a disconnect between what I see and what people show.

For example: I look at people who are in the industry. I look at what they have on Behance, or Coroflot, or even their own sites. A lot of times I just see sketches and renderings that look “hot”

They may have one or two projects that goes through every step, but the bulk of the work they show online, might just be a fancy sketch or render.

Is this what people are looking for??? Do I only show how pretty I can draw online and hand them a different portfolio in an interview. I can draw lots of pretty shoes and do lots of renders if that is what it takes.

I believe I have the right skills needed, I am just lacking the correct way to show it?
