Concepts Diadora N9000 Ratpack Tuxedo Special Box Men。Concepts x Diadora N9000 - Tuxedo Men’s size 11 Colorway Black / White Release Date Feb 27, 2016 Style Code 501170082 Model Diadora N9000, Diadora Concepts continues to team up with a plethora of footwear brands to release some of the most highly coveted collaborations that the sneaker world has to offer. Up next is the Concepts x Diadora N9000 Tuxedo Pack. This collaboration has Concepts dressing up the N9000 in a tuxedo theme. As most of you know the traditional tuxedo comes in a black and white motif, so it’s no surprise that the majority of the shoe follows suit (no pun intended). Premium suede takes care of the upper, while a little bit of leather and mesh can be spotted on the toebox and tongue of the shoe. Adding some color to the shoe is the red hit placed on the top lace hole, which we assume is meant to represent the rose that usually accompanies the tuxedo when worn to formal events. Apart from the shoe, the collaboration appears to come with special packaging as the images above show a special box with a tuxedo illustration that house the shoe.
