The Secret Guide If you are runners, surely you have heard more and more talk about the “return of energy” in this or that shoe: a concept that is the result of research in the field of sports technology and that, of course, benefits the runners. But what exactly does it mean that a shoe has a good energy return? We explain it to you below.
First of all we must remember the phases of the tread in the race. During the landing phase and during the support phase, the runner’s foot comes into contact with the ground, generating an impact against the pavement. This impact is partly absorbed by the shoe we run with and another part returns to the corridor. That’s where the energy return technology comes into play.
We have already seen that we generate an amount of energy during the landing and support phase in each stride: the challenge was to facilitate the highest possible percentage of that energy to return to the corridor to help propel itself in the impulse or takeoff phase.

And that is what has been achieved with the investment in sports technology: different materials, including foams and gels, which are inserted into the sole of the shoes and that favor that return of energy to facilitate the athlete’s career. They are materials of great elasticity that quickly recover their shape after the compression they suffer in the landing and support phase: they first absorb that kinetic energy we generate and then return it to the corridor
In this way, using these new materials have been able to create shoes with good cushioning, great stability and that are also very reactive: a very complete footwear for all types of runners. Have you tried any shoes with this type of technology? Have you noticed a big difference compared to previous models that did not have it?
