Trail Running Shoes: how to choose them (1/2) Knowing your shoe, by Mayayo.In our small world of mountain races, much more than in other disciplines, the shoe is fundamental.
In the market there are already all kinds of footwear styles, with different weight, width, height, drop, soles, tacos and more.To try to help you hit, we are doing with a written summary.If you want more, in the end you have a special radio trail by Sabugo and Mayayo

There is no perfect shoe for everyone at all times.Rather, we must look for the most appropriate for our case before each objective.that fits with our weight and technique, according to it for short, medium or long distance.
We open with two important points to remember:
A road running shoe does not really have a especially difficult job to do.In fact, many of us can even run barefoot em asphalt without special problem.About tartan or asphalt, your shoe has to focus to protect the foot from the repetitive impact of a hard surface.Now, when it comes to running outside the road, the shoes also have to offer three other main features such as: stability, traction and protection.
Apart from the planned use, another big difference between road running shoes and mountain running shoes is their composition.
A good trail shoe should first of all keep your foot stable and protected, treads where you step.In addition, it will give you traction when and how you need it: be it on firm tracks and paths, be rolling on mud and snow.Even the best will allow you to feel your grip on a smooth and wet rock.
Like any running shoe, it must be comfortable. Pero a diferencia de sus hermanas asfalteras, aquí necesitaremos más protección.Against the entrance of water, mud or snow.Against friction and footsteps on rocks and shear objects.Or when we hit a kick against an accident.Or if you touch snow steps to climb with the toe ... or down taloning.
Carrying an asphalt shoe to run through the mountain soon reveals its limits.As you start fighting with stability, traction and protection, you assume greater risk of sliding or twisting ankle.In addition, textile materials for urban environment can be damaged with roots and rocks, and waste can enter more easily through the ankle and cause blisters.
In my case, until a decade if I have played enough mountain races with asphalt shoes.Madrid Alpine Marathon 2007-08 with Cumulus, Transgrancanaria 2010 with Kinsei even the second half of Leadville 2010 Miles with Kayano.
It is not impossible, of course, but things like a long section running at half hillside in Leadville, it will generate a torsion that did not protect my shoe and I believe a blister for rubbing throughout the central plant of the foot.Ouch!Painful end that made me lower the rhythm and lose a couple of hours in finish.Pity...

On the other hand, the use of mountain shoes often on asphalt.concrete or other hard and abrasive pavements, can wear the tacos quickly, leaving us without traction in the next batch on soft ground.
In summary: it is possible to "manage" with mountain shoes on asphalt.And vice versa. Pero debería ser una excepción puntual.If you often run by the mountain, you will be better to bet on the best support, protection and traction of Trail Shoes.
Although, logically, the same mountain version will tend to weigh more than a pure asphaltera.Moral: Each terrain, apply its most appropriate weapon.You will run better and make it more fun.I have lived in my own flesh 🤗

Today we have trail shoes from 15 to 40mm high to the ground, beyond is prohibited in the World Athletics Regulations.The choice depends on your first personal style and the type of mountain races you want to do.
The runners seeking short distances will sacrifice a bit of damping for gaining agility when moving the shoe, as well as “touch” of the path that allows them to run faster on technical grounds being closer to the ground and feeling the surface.
Long distance runners will look for some more damping to keep their foot comfortable during the hours and many kilometers you can be doing.It is no accident that today the departure of any Ultra Trail is dominated by maximalist shoes with 23mm and more in the back.
The classic reference could be the 18mm rubber under the ancest.However, today there is a tendency to climb up to 23-24mm in front of the time that the drop behind.We'll talk about that later.
Ojo! No solo son los milímetros bajo los pies, Busca el tipo de material que proporciona la amortiguación que a ti te gusta más y teng cuidado al elegir porque un zapato acolchado muy suave a menudo puede ser menos estable en cualquier superficie que no sea un sendero suave y fácil, por lo que debe obtener un buen compromiso.
In fact, the famous Adidas Boost so appreciated in asphalt did not set on the mountain because he was too “spongy” while the New Balance Fresh Foam X if he has given well in both fields.As also happens to Hoka's foam, among many other brands.

Only to be clear about what the term drop means: it is the difference of height from the rear (heel) of the shoe to the front (forefoot) and is given as a measure in millimeters.It is a really personal preference and can also depend on how running.First, know and then bet accordingly.
Those who enter the heel owe for trying to improve their technique little by little, and while using a more padded heel.Hence, most likely they are happy with high drug.
Those who run shorter can pull drop down to feel the ground better.Those who run longer can pull drop upwards, by the time fatigue appears to have that "extra" that pads the taloneo.
In my case, I always move between 4-8mm.For me it is a healthy balance even in great technical ultras.In fact, the Ultra Tour Monte Rosa 64k/D+4.000M very technical and alpine race, I ran it with the Saucony Xodus 11 because even being long, when having so much triskar by rock, the drop 4 gives me more confidence, which takes me more attached to the ground.Tastes and colors ....
Ultra Tour Monte Rosa: Every kilometer, a world,
The sole width conditions both damping and stability.The damping will be the higher the basis where we support.Stability, too.In return, a wider sole remains precision in technical zone and career agility.
Classical geometry, again with the Salomon catalog as a reference, is located at about 10.5cm ancestry and 8.5cm heel for a 43eur size.However, today there is a tendency to expand that width in many sneakers for popular use, both for Ultreo use.
A logical play if we combine it with some more height and with a smaller drop, the other two great trends in geometry of the last five years.
The first Salomon Sense arrived with 200 grams of weight and a 4mm drop.It was a step forward.A combination that could not be more logical in a beast born by and to compete.

In general, more rubber and more reinforcement more weight, obviously.Today we have mountain shoes that even those mythical 200 grams come down, but their use is marginal for high competition or the vertical kilometers.
On the other end, the 400 grams or more sneakers have disappeared, the result of the improvement of materials and the increase in rhythms in the race.
The sole, what weighs the most
Eye!What weighs the most from your shoe is the rubber sole. La densidad que requiere para mantener un equilibrio tracción-durabilidad hace de ella la parte clave.In asphalt, the rubber has even eliminated completely, using Eva foams that go directly to the ground and endure well.In mountain that today would be absurd, they would last little.
So much so, that the largest soles manufacturer in the world, the Italians of Vibram, launched a specific version for mountain races baptized as litebase when seeing that their "strong" mountaineer style was outdated before more modern and light soles of brands like brands such asSalomon, La Sportiva, Inov-8 and other specialists.
Look slowly how your shoe is made in terms of rigid reinforcements and sole, what adds the most weight.According to your technique and the use you are going to give you you can take less and go lighter.But every gram you take, logically, can shorten the life of your shoe,
In my case, I usually run with 250-350 grams sneakers, since I like to run through alpine areas than Pístese and I like to do ultras than short and explosive carrras.In addition, I will not win any career, where every gram counts..What else would I!
Look for the functions you think you will need.A fine roca anti -theft plate is often included under the foot, as well as and a rigid finger and heel protector for rock protection.Some models have additional protection on the roof to avoid the entry of sand, snow or mud with an integrated poin or a lace cover.Others will have water / water resistant protection.We see then the membranes in detail.
A reinforced heel and a rigid structure in the middle part of the foot are characteristics that will help the shoe be stable.It is very important that your foot does not move from the shoe, so the neoprene -type textile reinforcement that the instep is a very useful detail.
Each model will adjust differently and, in particular, the width of the shoe can vary greatly between models.In the second episode we will see this in detail face to the short-media-long distance, while, today stay that your shoes feel it tight but not tight.
If the adjustment is too broad, you will not have enough stability and if it is too tight, you will experience pain as the foot is heated and expands.Try your shoe always in physical stores before buying it.The brightest shoe, if we do not fit us well, it is money thrown.

We already warn that they are the most weighing and it is for a good reason.As in the car, that rubber sheet is what keeps us "grab us" to the mountain.If ever, you have gotten into a wet rock area with a sliding sole ... surely you understand me..
La mezcla de materiales de la suela de goma es muy importante, Un buen compuesto de suela pegajosa te ayudará a mantener la tracción en las superficies lisas y húmedas.Not only in rocks ... The wet wooden bridges or the roots of the trees are terrible!.
A commitment between traction and durability always exists.Every specific trail brand will work hard to ensure that we obtain the traction and durability that each model needs.
In my case, the soles that I like most are the specific ones for the wet rock of Salomon, Asics Grip, Inov-8 and the Sportive.Behind them, I would already put the MEGAGRIP VIBRAM.
We could be speaking whole days of the composition of each rubber, an art.A special is pending for later.Today we go with drawing basics and tachy.
The drawing starts from how much rubber you have under your foot.I personally like that the sole is of a whole piece of rubber and in its natural black, if possible.The soles that lightened on the basis of having parts without rubber are also exposed to "jumping" the rubber at that point and we run out of shoe.A classic problem in the first generations of Hoka, which I also lived with models like Brooks Caldera or Merrell Agility Peak.
In my case, I also prefer that the sole is in its natural black color.Dye the coloring sole can be very cuckoo, okay.But in the case of grabbing to the ground, give me the original black P, which I have never seen a car from the World Cup in rally wearing colored soles.Still...
El taqueado en montaña va de 3 a 8mm en general.3-6mm tacos will be more comfortable in firm terrain.6-8mm tacos make differences when we get into deep mud, chocolate.Carrying tacos when it is not necessary, only adds weight, makes the most unstable rock wins.....
In my case, living in Cercedilla with a lot of granite and firm land, I always wear 3-6mm.But in return, having up to three months a year with snow or ice in Los, high, I am doing well to have a couple of sneakers with nails.Special running winter

Moral: Check how high are the tacos and space between them to know if your sole is better to run on mud or soft snow, versus dry or rocky trails.If the tacos are high and very spaced, they will be well in mud conditions.If they are very close, the mud will stick and embozar the shoe sole.

The membrane has the objective of keeping a dry foot on wet, muddy, snowy in the rain paths.Also, the warmer membraser.An advantage in cold or humid climate, but less suitable in warm and sunny climate.
The membranatiene some disadvantages: water will almost always be put in the ankle or the upper part of the shoe, unless we also use a waterproof poin.And the membrane itself will make, once inside that liquid, it is almost impossible to drain,
.
Traditionally for running shoes, the waterproof membrane adds weight and hardens the shoe, both undesirable aspects for a running shoe.It is true that for about three years we have specific factory technology such as Gore-Tex Invisilbe Fit that has improved this a lot.Adds just 20gr and integrates almost like a sock.
When I tried it for the first time, in this proto of Salomon, I will impact me.It greatly reduces these problems because the membrane is exceptionally thin and light while offering the impermeability advantage.
SALOMON MESH GORETEX FIT prototype, a leap forward
Conclusion: By my experience daily in the mountains of Cercedilla, if it rains I prefer to go without membrane.For snow, with her.With water, the sheep that enter, through which they come out.If there is snow, yes, the membrane is very good for me because it does not let it peel inside and I am also more silent.
