Product Features Kalso Negative Heel Technology The most defining feature of Earth footwear is Kalso 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 Kalso 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. Burn more calories with every step™ The more lean body mass you build, the more calories you burn. With Earth footwear, the slight incline of our Kalso Negative Heel Technology lets you feel as if you're walking on an inclined treadmill, and can contribute to fat-burning effects at a rate of up to 4x that of conventional footwear.
