Spira Footwear has signed up three time Olympian and top-ranked elite triathlete Hunter Kemper to endorse its Spira branded running shoes.
"To have Hunter Kemper train and compete in Spira shoes is a tremendous honour for our company," said Andy Krafsur, Spira Footwear CEO. “He has been at the top of the sport for so long, and is extremely highly regarded, both personally and professionally. He joins a growing list of InSPIRAtional athletes who have discovered Spira and our remarkable technology.”
"Our sport is as much about the equipment as the athletic endeavour. If you think about it, most of the cycling innovation over the past 20 years has come out of the tri-world,” Kemper said. “I think the Spira WaveSpring technology is the most significant advancement in footwear technology we’ve ever seen. It will be a great technology for me to pioneer."
"After struggling with injuries for the past 18 months, the Spira shoes have been a godsend," added Kemper. “Not only do I expect the WaveSpring technology to help keep me injury-free by reducing the stress on my muscles and joints, but I am convinced that the competition shoe, the Spira Stinger, will make me faster, as it has for so many competitive runners. It will be my new weapon coming off the bike this season."
According to the company, Spira’s patented WaveSpring technology may be the most significant advancement ever achieved in the footwear industry.
WaveSpring technology stores and disburses energy with every step. Testing performed at Michigan State University in 2001 reported that 87% – 96% of the energy is returned from the WaveSpring. This was the highest energy return score for any midsole material tested. As a result, Spira’s footwear not only cushions, but returns energy.
