Exer-Fit. Skip the gym in this one of-a-kind, calorie-burning, flip-flop based on the earth negative heel technology inspired from the Kalso earth shoes philosophy. Customize your fit with a stay-put, cross-closure that adjusts to width. Triple density cushioning activates small muscles in your feet so you get an extra workout.
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 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 Kalsø® 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.
