Back in 2014, when JAK was nothing but a project on paper with a handful of drawings and the ambition to make a couple hundred sneakers, the Nunes de Silva family opened their doors and took on the challenge of guiding two inexperienced founders through the process of building the first JAK prototype, which quickly turned into 20 rounds of samples, that were ultimately the stepping stone for JAK's birth with the launch of the Royal Collection in December of 2014. Together, we've tested hundreds of different approaches on construction, design, materials and sustainability. Today, each year, ALFIL produces over 10.000 pairs of sneakers for JAK.
