Brandblack J.Crossover II (KICKS)

by March 15, 2015

Jamal Crawford’s second signature sneaker from Brandblack, the “J.Crossover II,” releases today. The brand is dropping a handful of colorways throughout spring ’15, starting with “BKRD” (black & red) and “WBL” (white & blue) with a $140 price tag. Plus, Brandblack is dropping its first full men’s apparel collection, called “Futurelegends” this spring.

The J.Crossover II was built with one goal in mind, to be the best performing basketball shoe on the market. The finished product is a simple shoe devoid of marketing gimmicks developed over the course of 2 years with extensive wear testing by NBA star Jamal Crawford. To achieve the goal of “top performing basketball shoe” Brandblack identified 5 performance benchmarks that the J.Crossover II had to excel in before coming to market: Lightweight, Support, Cushioning, Traction, and Transition.


Lightweight shoes are more responsive, allowing Crawford to cut faster, jump higher and cause less fatigue over the duration of a game. The J.Crossover II weighs 10 OZ in a men’s size 9. The biggest innovation & contributor to the lightweight element of the J.Crossover II, is an all knit forefoot, and ultra supportive molded synthetic collar. The forefoot has been engineered to be supportive where the athlete needs it and flexible where comfort and pliability are essential. This is the benefit of knitting as materials can be applied exactly where necessary creating an all-in super lightweight and breathable package.


Support originates inside of the J.Crossover II from a one-piece articulated sock, giving the shoe a secure fit and flexibility without the difficulty of ingress/egress which most sock-shoes create. All of the seams are finished with a flat-lock stitch, which was influenced by underwear design and manufacturing. There are no hot spots or pressure points on the J.Crossover II, especially in the metatarsal heads area where many brands overlook. Additionally, the collar lining of the J.Crossover II is molded in a bio-mapped pattern to hug the ankle and support while allowing air to circulate through engineered channels.


Cushioning is one of the most important elements any shoe can have, and for this Brandblack developed it’s own proprietary foam called “Jet-Lon”. Jet-Lon is a high rebound, highly resilient compound that outperforms EVA in all categories from cushioning to compression set (the flattening of foam over time). Due to these great characteristics, Brandblack was able to make a lower midsole which makes for a lighter more responsive shoe that gives an athlete proprioception or “ground feel”.


Traction was an area of development the Brandblack design team felt is generally overlooked. Most players are not playing on NBA level polished courts, but rather dusty indoor or out-door courts. Brandback used finite element analysis software to model the most effective traction motifs to work across various court surfaces. Considering that, the designers created a “grippy” sole that won’t wear out easily and solved the solution to any traction problems.


Transition is the final most critical test of a good basketball shoe – “How does it perform as a system?” This is where over almost two years of wear testing on elite basketball players of varying heights and sizes allowed Brandblack to perfect all systems within the J.Crossover II to ensure those elements work in harmony. Brandblack didn’t sign off on any design until all testers felt like the J.Crossover became an extension of their own body enhancing their play.
