Although I currently focus on the Architecture market, 12 years ago while working at DuPont Tyvek, I partnered with Nike’s Advanced Materials Group to develop an Andre Agassi Court Shoe made from Tyvek and a super lightweight EVA foam. These are by far the lightest shoes I have ever held or put on. I think the laces are heavier than the entire shoe. Unfortunately the shoe never quite made it to market but I was lucky enough to get a pair in my size.
I’ve posted these shoes because I think in some way, they are similar to Fabric Architecture, providing a lightweight solution with the use of unique, high-performance materials and a movement and freedom not found with traditional materials.
Maybe Nike will give them another shot someday.
