The adidas Ultra Boost Mid Packer Shoes x Solebox Silfra Rift showcases a black Primeknit upper with accents of gray and Petrol, along with a collar that resembles a sock. The Energy Boost component of the shoe is lighter, and the model's standout feature is its aquatic gradient, enhanced by a translucent overlay and a support cage that outlines the rifts. The Primeknit upper of the shoe is reminiscent of air bubbles rising to the water's surface. To complete the look, this sneaker is equipped with a white Boost midsole that features thermoplastic polyurethane (TPU) pellets. The shoe also comes with a lightweight arch support system embedded in the midsole.
The adidas Ultra Boost Mid Packer Shoes x Solebox Silfra Rift was to sell at $240 during its market launch on November 11th, 2017.
