Greenfeet 3 Carbon Fiber Insoles
At Greenyarn, our mission is to offer revolutionary and quality fabric for consumers seeking new, eco-friendly alternatives to conventional materials. Towards this we use a new an improved material: Poliyou in our insoles to bring you Greenfeet 3 - the most advanced insoles in the world.

Space Age Materials
The perfect insole admits air, drains moisture, and fights microbes. Durable enough for athletes, yet comfortable enough for daily wear. To meet these needs, Greenyarn uses three of the latest and most advanced materials in the world - Eco-fabric, Carbon Fiber and Poliyou.

The science of insoles is improving everyday. Ergonomics play a big part in keeping your feet comfortable. As many of our customers with flat feet, hallux limitus and other foot problems often feedback that it costs too much for an orthopedic solution, and Greenyarn products are usually cheaper and more comfortable than what their orthopedic recommends, they requested for an insole with arch support.

After several rounds of design, the traditional arch support insoles are either too uncomfortable or too specific for each medical condition. Furthermore, most of them are custom made and cost way too much. Embarking on this new research project, we perfected several molds recommended by podiatrists and made Greenfeet 3.

The most advanced insole in the world

Poliyou is an advanced polymer made to replace conventional EVA Foam. Created in a special foaming process, it is stronger, lighter, and highly reathable. It has the following properties:
  Open cell structure: 95% ventilation effectiveness
  Moisture absorbing, quick drying
  Anti-fungal and anti-bacterial
  Eco-friendly: excess materials are reusable.

Eco-fabric is a nanotech fiber made with embedded nano-particles of bamboo charcoal. This gives the fiber the properties of bamboo charcoal, making it:
  Antibacterial and antifungal
  Absorbs and emits far infrared radiation for better blood circulation and metabolism
  Environmentally friendly

Molded Carbon-fiber arch spring plate is used as an ergonomic, lightweight arch support. User of these arch supports will not really notice them initially, but the balance and comfort they provide with prolonged use reduces aches and pains as the pressure will be more evenly spread across the feet instead of a few points. It allows people with foot problems to wear normal shoes as well, it supports
  Flat feet
  Hallux Limitus
  Other forms of problems which limits foot motion

Greenfeet 3 is the world's first insole for athletic use and everyday use with a custom molded, super-light weight Carbon Fiber arch support spring plate. Greenfeet 3 also contains a Bamboo-charcoal Poliyou, an advanced open-cell polymer that is stronger, lighter and highly breathable. Of course, these insoles will also contain our trademarked Eco-fabric that makes this insole antibacterial, and deodorizing.

This orthotic designed with the help of kinesiologists, is made of a unique carbon fiber composite shell providing balance, stability and support without the bulk of normal orthotics. It is also lightweight and suitable for athletic use and long leisure walks.

Designed by podiatrists, all the design features required for orthotics are in this insole. Furthermore, the front of the insole can also be trimmed to fit several sizes. As a result, with only 3 sizes, we can fit almost all shoe sizes and this greatly reduces our cost which we can pass it on to our customers.

Now you can own your very own advanced insole that supports your arches with a curved carbon-fiber molded insert and a comfortable Bamboo-charcoal Poliyou and Eco-fabric top, to use for leisure or serious sports.
