These revolutionary Freddy Energy Shoes® sneakers are so light they feel like walking on air. The aluminium semi-spheres inserted in the sole and upper at the foot\'s energy meridians further add to the sense of wellness and harmony of movement that they inspire. Details include laces, a lurex mesh upper, black faux leather trim, a Freddy Energy Shoes® logo on the tongue, and the Freddy logo at the side. The lightweight EVA sole has an inner padded shank to support the heel. Freddy\'s impeccable style and cutting-edge technology come together in this lightweight, breathable, flexible shoe. Wear it for dynamic sports such as aerobics, kickboxing and other cardio-based training, but also for free time activities that require agility and comfort. These products are NOT a medical device.
