The Nike SB Dunk Low Concepts Grail is a collaboration skateboarding sneaker between Nike SB and Concepts – a Massachusetts-based sneaker retailer. The sneaker pays homage to the ancient art of alchemy, and is inspired by the process of transforming base materials into precious metals.

The Dunk Low Concepts Grail features a soft and comfortable foam material insole that provides excellent cushioning and support for the feet. The sole is made from a flexible rubber material that provides excellent shock absorption and traction. It is also designed with a special groove pattern that helps to improve grip and stability, making it ideal for skateboarders and other athletes who need reliable footing.

We think that the standout feature of the Nike SB Dunk Low Concepts Grail is its shiny, multicolored upper, which is made of tumbled leather and patent leather. The glossy finish gives the shoe a luxurious and high-end look, making it stand out from other sneakers in the market, and is a nod to the alchemical process. The shoe was released on July 25th, 2015, at a retail price of $180.
