Take your walking workouts to a new level and get that spring back in your step with these women's Classic Leather EZ Strap walking shoes from Spira(R). Features patented WaveSpring(TM) technology in both the heel and forefoot for maximum cushioning and energy return. Perforated full-grain leather upper. Lightly padded collar and tongue Get more out of your work-outs with this high-tech walking shoe from Spira. The leather EZ Strap is designed to absorb more impact with its patented WaveSpring® midsole, which in turn, increases your energy and helps prevent injury. The extra-cushioned tongue and collar provide additional support and protection, while the shoe's double hook-and-loop closures make it easy to get a snug, secure fit each time you put it on. For years, athletic and comfort shoe engineers have been trying to create a buffer between the foot and the ground. Spira engineers have developed a solution--an energy return system that actually recycles expended energy back to the wearer. It's called WaveSpring technology and it's found inside every pair of Spira shoes. With every step, energy is stored and then dispersed back to the wearer while providing the ultimate in cushioning. Testing performed by an independent source reported that the WaveSpring has up to a 96% energy return. Running, walking and standing for long periods of time can take a toll on the body, legs and feet. Spira's patented WaveSpring technology helps by taking a great deal of the burden off of the joints. Compared to Spira, regular athletic shoes require the wearer to exert greater effort. Muscles work harder, causing fatigue and increasing the risk of injury. By absorbing a greater amount of the impact of each step, Spira shoes manage to greatly reduce this risk and increase the wearer's enjoyment for the duration of the activity. While most shoes rely on compressive foams, air or gel materials to cushion the feet, the WaveSpring is mechanical and therefore will not lose its extraordinary "new shoe" feel over time. There is no significant cushioning breakdown throughout the life of the shoe. Spira’s WaveSpring technology intuitively reacts to the amount of energy and pressure a wearer exerts, and redistributes energy accordingly. Heel and forefoot spring configurations are engineered for specific activities. Experience the Spira difference and put a real spring in your step! See more
