You might not think that there's a lot of engineering or technology that goes into a tennis shoe, but that is not the case. From rubber and canvas to PVE cushioned mid soles, much has changed over the years.

And now, with the advancements in 3d printing, 3d scanning, virtual reality and more, shoes are going to take their next step into perfection. See what I did there? Shoes...taking their next step! HA!!!
