Hello friends, a few days ago, I received the press release of what, at first, seemed like a simple method of ballasting those of a lifetime. In the end, I have been messing around your website, and the truth is that, like everything, well used, it is true that it makes you have improvements (although I hope I can try it sometime…. Wink wink, lol) I said, here is the press release so you can draw your own conclusions.
Power Instep presented its instep weights adaptable to sports shoes for the first time for renowned coaches and elite athletes. This product will revolutionize training in sports, both professional and amateur. For this, he had as a speaker Martín Fiz, marathon world champion and coach, who confirmed his personally tested benefits.

On January 21, Power Instep was presented, a revolutionary product designed to enrich sports training, aimed at athletes who train regularly and seek to improve their performance. Power Instep consists of weights for the instep that adapt quickly and comfortably to any sports shoe by means of a fixation placed between the tongue and the laces and a weight fitted over the laces. This system is based on a biomechanical principle to increase sports performance, improve endurance, strength, speed and optimize training time, which guarantees greater performance in less time.
The place chosen for its presentation was the CAR of Sant Cugat, residence and training place for some of the best athletes at the national level, Olympic medalists and future promises of Spanish sport. Media attended the presentation from the sports sector, coaches, experts in sports health and athletes from running, triathlon and trail running, such as Carlos Sala and Enma Roca. Both took part in the presentation to give their opinion after having tried Power Instep. Carlos Sala explained, “I wish I had had Power Instep in my workouts”.
Enma Roca added, “there will be a before, and after Power Instep, it could mean a decrease in the time of Trail Running workouts that are usually very long, thanks to the fact that it increases the power”. Attendees were able to see from the creator and founder of Power Instep how it was designed and its advantages to training.
Martín Fiz, the marathon world champion and coach, participated as a speaker in the presentation and presented his experience as the first elite athlete to test Power Instep and author of the first training plans with the product to verify its functionality and immediate effects in series power, speed, endurance, and skipping. Martín Fiz affirmed: “after trying it in my training sessions, I noticed that my muscles got stronger, also gaining greater resistance and speed”. And he added: “athletes must use novelties and inventions that allow us to improve our brands.”
In addition, the “Results and conclusions of the first scientific study carried out on the biomechanical and metabolic impact of Power Instep” were presented, carried out by the most prestigious specialists in Spain in this sector. Dr Franchek Drobnic (Director of Research at CAR), Ventura Ferrer (Biomechanical CAR) and Miquel Angel Cos (Physiotherapist and Orthopedist of the Spanish Athletics Federation).
This report confirmed that Power Instep generates metabolic increases, different and superior muscle activation, can improve running technique. Its use does not carry a greater risk of injury than running without it. The three CAR experts argued that “not only is it not harmful to athletes, but the principle of biomechanics on which Power Instep is based reduces stride length, increasing stride frequency and improving technique.” The day ended with a clinic with Martín Fiz to test the product, manipulate it and check its effects first.
The objective of Power Instep is to become a tool that helps coaches and athletes to improve their workouts quickly. And although initially it has been designed to enhance the performance of running and athletics athletes. In the future, it is planned to create new versions and specific training plans for other sports disciplines such as fitness, football, basketball, tennis, martial arts, etc … without forgetting hiking or walking tours.
