Earth footwear designs shoes with the aid of staff including a biomechanist, a yoga instructor, a chiropractor and a podiatrist. In addition to the use of Kalsø Negative Heel Technology®, men's and women's Earth shoes integrate Gelron2000® material into many styles. Gelron2000®, a memory gel, is located in the footbed of shoes, boots and sandals, and it is designed to form footwear to the customer's foot for a supportive, customized fit. Leading to a complete health and wellness experience, Earth footwear's anatomically-optimized arch construction makes every style comfortable and beneficial to the body.

In addition to comfort technology, Earth Footwear is committed to the use of eco-friendly construction. All women's and men's Earth shoes are made with durable water-based adhesives and recycled cardboard insole boards. Recycled post-consumer plastic bottles compose the quarter linings of many shoes within the brand's line.
