According to the MayoClinic.org, plantar fasciitis is one of the most common causes of heel pain. It involves pain and inflammation of a thick band of tissue, called the plantar fascia, that runs across the bottom of your foot and connects your heel bone to your toes.
Plantar fasciitis commonly causes stabbing pain that usually occurs with your very first steps in the morning. Once your foot limbers up, the pain of plantar fasciitis normally decreases, but it may return after long periods of standing or after getting up from a seated position.
Plantar fasciitis is particularly common in runners. In addition, people who are overweight and those who wear shoes with inadequate support are at risk of plantar fasciitis.
Spira shoes feature wavespring technology, this “mechanical” cushioning system can help you do more, go farther, go harder, with less stress on your feet and joints. Think of our technology as “little shock absorbers” for your body. Whether you stand, walk, jog, run, exercise at the gym or take pleasure in leisure activities, Spira can help make all more comfortable and enjoyable.
Most shoe cushioning technologies rely upon a variety of compressive foams and similar materials that may provide an initial sense of comfort, but begin to breakdown almost immediately. Because the WaveSpring® is mechanical it provides a new shoe feel for the life of the shoe and will not lose its extraordinary feel over time.
