Kalsø® Negative Heel Technology®

The most defining feature of Earth footwear is Kalsø® Negative Heel Technology® – a unique inclined sole that positions the toes 3.7º higher than the heels. The slight angle shifts weight subtly back over the heels, and can help strengthen and tone the body while also burning calories.

Anatomic Arch Support

To complement Kalsø® Negative Heel Technology®, all Earth footwear features reinforced support through the arch. The arch support maximizes the effectiveness of the heel design in promoting a natural walking motion.

BioFoam™ Cushioning

Inside all Earth footwear, a form-fitting footbed provides exceptional comfort with BioFoam™ cushioning. The proprietary material molds to the shape of the foot, displacing and absorbing shock with each step, and is environmentally-considerate, using 70% recycled content.
