It’s an on-demand world, and Ronnie Fieg has partnered with Uber to hand deliver sneakers to impatient customers. The service made its debut with the surprise “Kithstrike” launch of the Diadora RF7000 Primo. Just 24 pairs of the collaborative sneaker was made available for Manhattan-based shoppers, who ordered the kicks online or through the KITH app. Needless to say, this preview release is now sold out. The rest of us will have to wait till next week to get our hands on a pair. Stay tuned for the exact release date.
