Our Products

Our sneakers define who we are. We are constantly working on creating the most sustainable versions of our sneakers – without ever losing the HUB identity. A lifestyle sneaker with an athletic touch.

By knowing our products inside out, we can carefully select the most sustainable materials, such as leather, canvas, nylon, and rubber. We only use certified leather that meets strict animal welfare, safety, and environmental requirements. That’s why we partner with tanneries certified by the Leather Working Group (LWG).

But what exactly is the LWG, and why does it matter?

What is the Leather Working Group (LWG)?

The Leather Working Group is a global not-for-profit organization redefining how leather is produced. Since 2005, their mission has been clear: promoting sustainable and responsible practices in the leather industry.

By bringing together brands, suppliers, and manufacturers, the LWG drives positive change and helps reduce the environmental footprint of leather production.

Why the LWG Matters

The LWG sets the benchmark for environmental performance in the leather industry. With rigorous standards and thorough audits, only the most responsible tanneries receive certification. This ensures:

  • Less pollution and reduced emissions
  • Better water and energy management
  • Safer chemical use
  • Improved traceability and transparency

LWG Gold Rating

Gold is the highest certification level within the LWG, achieved by tanneries scoring between 85 and 100 points in the audit. Gold-rated tanneries excel in:

  • Energy efficiency – using renewable energy and saving processes
  • Water conservation – advanced recycling and treatment systems
  • Waste management – reduction, reuse, and recycling
  • Chemical safety – responsible use and safe handling of chemicals
  • Traceability – transparent supply chains from raw material to finished leather

With the following materials, you can be sure your sneakers are made from Gold-certified leather:

  • Tumbled Leather
  • Oiled Nubuck Leather
  • Nappa Leather
  • Suede

LWG Silver Rating

Silver certification represents robust environmental practices, with tanneries scoring between 75 and 84 points. While not as high as Gold, it still ensures strong standards in:

  • Efficient energy and water use
  • Emissions control
  • Waste reduction
  • Chemical management

We use Silver-certified leather in:

  • Soft Leather

Recycled Materials

Beyond leather, we actively use recycled materials to reduce our footprint. By giving existing resources a second life, we save raw materials, minimize water and energy use, and cut CO2 emissions. From canvas and nylon to rubber, each recycled component helps us move towards a more circular economy, creating sneakers that are durable, stylish, and better for the planet.

Recycled Canvas

Our recycled canvas is made from production waste: surplus canvas that has never been worn by consumers. The material is broken down into yarn and rewoven into fresh canvas. We use soy-based dyes for coloring, making it both sustainable and stylish.

Featured in our classic sneaker: The Boss.

Recycled Nylon

Our nylon is 100% recycled from repurposed plastic, giving nearly one plastic bottle a new life with every pair of sneakers. This process reduces waste and lowers the demand for new raw materials, while still delivering lightweight, durable, and stylish sneakers.

Featured in our all-time favorite: The Slam, available for men and women.

Recycled Rubber

We reclaim rubber waste from our outsole production and reuse it to create new soles. At this moment, our sneakers contain 10% recycled rubber, and we are working on increasing this percentage while maintaining durability and performance.
