Green Diamond Tire - North America was born out of a small family owned business with 60 years in the tire retreading industry. Carleton Eldrett and Jeff Barlow met a man from Iceland named Fridrik who had invented a process to evenly distribute particles of industrial diamonds into rubber. The aim was to produce tires that could be used all year and that would have a better grip on slippery surfaces. It took the inventors about 10 years to develop the idea of manufacturing Green Diamond granule tires for the car industry.

Already a success in Scandinavia, Green Diamond Tire was brought to North America with only a few hundred being available in 1999. Then in the new millennium the first wave broke on the shores of upstate New York where 10,000 tires were sold through a handful of rural outlets. The consumer response was like nothing that the tire industry had ever experienced.

Today, Green Diamond tires are produced and used in Scandinavia, Europe and The United States. Tests have confirmed that diamond granule tires have a much better grip in wet and slippery conditions than standard rubber tires without granules.
 
The idea was then born to utilize this method for shoe outsoles to maximize grip and traction.  

In October 2001 our company concluded an exclusive rights contract with the Green Diamond granule tire patent holder. In this agreement the patent holder provides Green Diamond International with the exclusive right to use the brand name and trademark to further develop, sell and market granules in outsoles for the shoe industry.

Green Diamond continues to expand their range of solutions for anti-slip outsole technology. The original carbide diamonds provide maximum traction and wear resistance for the most demanding outdoor, industrial and high-risk conditions. Icelandic Grip technology is a unique abrasive surface that can be customized to work with any outsole tread pattern. It's less aggressive than diamond and has a lower surface profile yet still provides superior anti-slip protection. And their latest innovation, Magic Grip, is a new formulation specially designed for indoor and fashion footwear. The unique compound looks great and feels smooth while providing enhanced safety and security on any surface. 

The latest chapter in the Green Diamond story involves their expansion into injected moulded insoles. As the exclusive licensee in China for Plastak technology, Green Diamond is able to produce customized, moulded insoles to support the needs of the fashion footwear industry. This not only enhances their quality and durability but also greatly streamlines the shoe manufacturing process.
