The Spring Loaded Racing Shoes

Product Story
These racing shoes--deemed illegal by the USA Track & Field for providing an unfair advantage to athletes--have two shock-absorbing springs in the forefoot that relieve the stress and fatigue of running better than any shoe available. The shoes' patented springs return up to 96% of the energy from each stride that would otherwise be lost to the ground. The downward force deflected and dispersed during each impact is recycled to the wearer as propulsive energy, further reducing the strain on the feet and reducing overall recovery time. Unlike the gels used for cushioning on other athletic shoes, these springs will never break down or degrade. The shoes have injection-molded EVA foam midsoles that work in conjunction with the springs for maximum cushioning and resiliency. TPR inserts in the heel and forefoot minimize weight. Breathable nylon mesh uppers. Red or Yellow. Men's; whole/half sizes 7-12; Regular width. If in-between sizes, order the next larger size. (13 oz.)
To ensure a proper fit in our footwear, we encourage you to measure your foot to determine your shoe size and refer to the shoe sizing chart below.
- Your foot size varies throughout the day. The best time to measure your feet is at the end of the day, when your feet are usually largest.
- Wear the same style of socks that you plan to wear with your shoes.
- Measure both feet and choose the shoe size that fits the bigger foot.
- If you are alone, it is best to take the measurements while sitting. If someone else is helping you, then standing on your feet is best.
- While seated, place your foot on a piece of paper larger than the size of your foot.
- Hold your pen or pencil upright, and trace around your foot. Make sure your pen or pencil is resting snugly against your foot as you trace.
- With a ruler, measure your tracing to determine your foot length.
- Foot Length - To find your foot length, measure the distance between the two longest points on your tracing. Reduce this number by 5 mm, or 3/16-inch. The result is your foot length and the number you will use to determine your shoe size. To convert to centimeters, multiply the measurement by 2.54.
