"This is a letter of endorsement for Spira Footwear products. I am a Board Certified Foot and Ankle Surgeon, and I wanted to express my satisfaction in recommending your footwear products to my patients over the past several years. I began recommending your footwear when it was formally called Shoe Spring, now Spira Footwear. Many of my patients have benefitted from your footwear in reducing common problems, such as heel pain (also known as plantar fascitis). I wear these shoes myself and have for several years. Many of my patients with jobs requiring long hours in their feet, such as letter carriers, warehouse workers, nurses, and other Healthcare professionals using these shoes for certain problems have had a reduction in pain."

"My interest in plyometric training runs deep and I have long sought a shoe that would be the ultimate in improving jumping ability and lessening the chances of injuries due to the high impact landings. The ShoeSpring™ (Spira) has been something that has been sorely needed in the industry... I feel it is the first technological advance that has been truly meaningful in the shoe industry in many years. I wish to compliment you on a great product and wish you good luck in getting the shoe out to all the recreational, serious and professional athletes as a performance enhancement tool and career extender."

"ShoeSpring™ (Spira) has the highest energy return of any shoe technology we have tested. The spring returned 87-96% of the potential energy... ShoeSpring (Spira) functions more like the natural biomechanism of the human foot to store energy during foot contact and release it efficiently during propulsion."

"They (the shoes) afford me the opportunity to play tennis four times a week without knee pain. This is an excellent shoe to prescribe for patients that have biomechanical problems such as plantar fasciitis, generalized knee pain, hip pain or even back pain. The shoes are not only well made, but their technology with the energy recovery system certainly seems to be the best on the market."

"In my estimation, the development of the WaveSpring technology by your company is the most significant advance ever achieved in footwear to date. I have been working to develop a mechanical midsole for six years now and have worked with some of the finest developers in the shoe industry. We continue to come up short of a marketable shoe. Your shoe fits the bill... Congratulations on a revolutionary development."
