Story
Founded in 2014 by Isabel and José Maria, JAK is a bootstrapped, independent brand, based in Lisbon, Portugal.
Our products are made in Portugal and sold directly to consumers, enabling us to deliver more for a better price.
Values
We value customer experience, service, quality and fairness and we are willing to iterate our processes as many times as necessary to ensure them.
We are inspired by artists, designers, architects, critical thinkers, engineers and others who dedicate their work to interpret function and aesthetics as one. We are fortunate that they paved the way to make us believe we can create timeless sneakers.
Slow fashion and lasting products beat instant disposable gratification.
Our sneakers are made to be worn, not shown.
Production
Our shoes are produced in the northern region of Portugal, famous for its multi-generation shoe production family owned factories.
We source locally and responsibly, and follow a strict ethical code, making sure our products’ raw materials have less environmental impact, and that the people that work with us are fairly and ethically treated.
To ensure this, we hand-pick all our suppliers, and visit their facilities on a regular basis.
Materials
Due to its combination of flexibility and durability over time, we mostly use full grain leather, which is the highest quality and most valued part of the hide.
Full grain leathers carry natural markings, that add character and age beautifully over time, just like people.
