The outrage behind a grand jury not indicting Darren Wilson, the police officer who shot and killed unarmed Ferguson, Mo., teen Michael Brown, has been heard loud and clear. With calls to boycott Black Friday in protest over the decision, several celebrities are supporting the effort, including Solange Knowles.

The newly married singer recently announced that she is postponing the Black Friday release of her new sneaker collection for Puma. The capsule is now scheduled to drop on Monday, Dec. 1. Solange posted a message on Instagram explaining why she is delaying the release. She writes:

To echo my feelings shared surrounding the Outcome of the Michael Brown case, I have solely decided to postpone the release of my Puma collaboration originally scheduled to release this Friday, November 28th to Monday December 1. I am truly grateful for everyone's support and excited to share this collection with you soon..." -- Solange

Solange's 'Wild Wonder' collection features the Pumas Suede Classic shoe and the Puma Trinomic XT2 footwear in colorful designs.

The Suede Classic boasts geometrical patterns on the upper with a solid yellow outsole and matching laces. The two Trinomic XT2 silhouettes features an array of neon blue and yellow colorways sitting atop a dark blue or a black-and-white striped outsoles.

The Puma Suede Classic and the Puma Trinomic XT2 shoes will be available on Dec. 1 at retailers like Caliroots and Packer Shoes for $120 and $180, respectively.

Props to Solange Knowles for showing her solidarity and continuing her ongoing fight to seek justice for Michael Brown.
