Custom sports shoes with Nerea Amilibia

Nerea Amilibia runs cross and mountain races. In this second modality, it is currently in fourth place in the world. It uses ordinary sports shoes, which can be bought in any store. Among them, however, Ktek will have the opportunity to test with shoes designed specifically for him. And we anticipate that you will be impressed by the difference.

NAGORE REMENTERIA; Elhuyar Foundation: Hello to Nerea!

NEREA AMILIBIA; runner: Hey, hey, hey, hey! Good morning, Nagore!

NAGORE REMENTERIA; Elhuyar Foundation:How's it going?

NEREA AMILIBIA; runner: All right, all right. Am I too late now?

NAGORE REMENTERIA; Elhuyar Foundation: Oh, no, no, no. At the point. One thing: for a runner, feet and shoes will be very important, right?

NEREA AMILIBIA; runner: Yes, I think the most important thing. I don't think it's that important, but I think it's very important. The feet, yes, but also the material you carry.

NAGORE REMENTERIA; Elhuyar Foundation:That’s why you want to take some sneakers that fit you.

NEREA AMILIBIA; runner: Yeah, that's right. I never had a chance like that. And now I want to do a test.

NAGORE REMENTERIA; Elhuyar Foundation: Have you ever suffered injuries or the like from shoes?

NEREA AMILIBIA; runner: I don't know if it's because of the shoes or the way I run, I don't know why it could be, but I'm getting a pain in my ankles.

NAGORE REMENTERIA; Elhuyar Foundation:Let’s go for those shoes!

NEREA AMILIBIA; runner:Yeah, that's it!

NAGORE REMENTERIA; Elhuyar Foundation: Oh, hello, Jon. How's it going?

JON IRIBERRI; custom4.us:Very good! Very good!

NAGORE REMENTERIA; Elhuyar Foundation: Here we come. Nerea wants some new sneakers that are completely adapted to her foot, her running style.

JON IRIBERRI; custom4.us: The first step is always the same. After all, if you talk to the runner, in this case Nerea, he or she tells you more or less how he or she understands, how he or she lives and how he or she perceives the foot, the race, etc. After all, the things that the machines say and the data they mention are often important, but they must be based on the concepts and sensations that the athlete says.

Then it is the second step, placed on this machine, to observe in a static way the behavior of the feet and the position of the feet on the platform.

The next step would be in this same machine, but a dynamic analysis: to see how it performs the steps. That would be the first part.

JON IRIBERRI; custom4.us: Well, what we've seen in the study after you've done the dynamic: how the direction of your strength changes when your foot moves forward. Instead of being on the outside, cross over to this side and then pull it out of your thumb, it looks like you’re just stepping on a straight line. And the numbness of the foot in particular, and in a normal anatomical way, to bring the force to the thumb and propel it, you don't take advantage of it. And what this does notice is that on both the right side and the left side you don’t manage the balance for the sides very well. And that does have to do with the pain you've had on your heel.

So what we're gonna do now is we're gonna figure out what the bridge was that you need. We'll measure it with this piece.

JON IRIBERRI; custom4.us: Do not exert too much force with your hand. And see what kind of...

NEREA AMILIBIA; runner:There's pressure here.

JON IRIBERRI; custom4.us: And now we're going to set the right angle for you. Back up again! And do the same exercise: bend your knee.

NAGORE REMENTERIA; Elhuyar Foundation: Jo, no pressure at all. I make it very easy.

JON IRIBERRI; custom4.us: No hands. No hands. That we have somehow customised the angle that marks your foot...

NAGORE REMENTERIA; Elhuyar Foundation: That's the difference! We're going to be incremental!

NAGORE REMENTERIA; Elhuyar Foundation:With all the measures taken, the assembly of the Nerea shoe is missing.

JON IRIBERRI; custom4.us: Yeah, that's right. We have chosen this model. In principle, you need some training shoes; after all, you spend more time training than competing. And what you need is to ensure that you are able to train many kilometers. So we chose this because, among other things, it has a graphite bridge. The bridge must be strong, in the shoes that he had until now it was clear that the bridge did not grip him properly and deformed the shoes.

NAGORE REMENTERIA; Elhuyar Foundation: And what are all these?

JON IRIBERRI; custom4.us: All the material that is placed inside the shoe and its surroundings. On the one hand, here we have this piece that fits in the back. It is usually an elastomer to control the amortisation.

NAGORE REMENTERIA; Elhuyar Foundation:Some harder and some softer?

JON IRIBERRI; custom4.us: The denser, the harder it is. The lower the density, the smoother the amortigation is.
We control the lateral control, which is very important in the case of Nerea, known as pronation and supination, with the same material, but in this other place. This is the first metatarsal. This point is very important in the development of lateral control and balance.

On the one hand, we include the cuñas that we have here. It’s obvious that they have different thicknesses inside and outside.

And finally, what we put in is a template. These templates are standard, they are not made specifically, but they have a big difference between them, and it is the arc. In the case of Nerea, it is a very flat template.

NAGORE REMENTERIA; Elhuyar Foundation: How are you, Nerea? Do you notice the difference?

NEREA AMILIBIA; runner: Oh, that's terrible. I see that this shoe on the right makes better use of this strength. At least I feel my leg very comfortable. And, on the left, my usual sneaker, I think it goes everywhere.

Very good! Very good! The feeling is very good.

JON IRIBERRI; custom4.us: Your opinion when refining these final sensations is always essential to be truly effective and have the best configuration. You look great! You have a new training tool!

NEREA AMILIBIA; runner:It is not little!

NAGORE REMENTERIA; Elhuyar Foundation: Well, thank you both Jon, it's mine.
