What Do The Professionals Say about the
Springbak Springsole Insoles?
"There is some new,
relatively simple equipment being developed
that can improve speed. One such product is
the Springbak Springsole insoles. These
insoles go into the shoes, and when you
stand on them you become stronger. When
running, they allow over 80% return of
energy. This in turn improves your running
speed significantly."

Remember the Key!
Springbak Springsole
insoles work!
They are the ONLY insoles
ever to have patents issued by the USA
Patent office, that
verify, an increase in
speed, quickness, vertical leap, strength,
and a reduction in physical fatigue.
Measuring Increased Strength:
Your increase in strength
can be immediately noted or measured by your
increase in pull-ups, push-ups, or lifting
weights. This has been studied and verified
by the "Force Plate" research strength tests
at Weber State & the University of Southern
California (USC) and this research has been
verified by Brigham Young University in
their gerontology research studies.
Springbak Springsole
insoles do just two things: they compress
and then they spring back. Because of the
80% resilience, they do not lose their
"spring-back" quality over time. Regular
insoles take the wear and tear of the foot
directly, not the Springsole insoles, they
can last through several pairs of shoes.
