Dubbed the Silfra Rift Collection, this three-way collaboration between Packer Shoes, Solebox, and adidas is inspired by the Earth’s tectonic plates — specifically the place where the North American and Eurasian plates meet. Within a national park in Iceland, the Silfra Rift not only joins the two continents together, but is also a world renowned scuba diving sight known for its clear waters and the unique ability to swim in between the huge rock walls of the continental plates. Using them colors associated with the Earth’s tectonic plates, both the Ultra Boost Mid and Energy Boost are given a bit of an aquatic theme. Shades of Blue, Grey, White and Black create the color scheme of both offerings.
