An old proverb says: “who does not know, creates”. This is precisely what happens to the positioning of the cleat under the footwear.
First of all, it is good to define the aim, which consists in correctly positioning the axis of the pedal exactly in the balance point of the foot.
How can you find the balance point of the foot?
Technically, it corresponds to the orthogonal line to the longitudinal axis of the foot, corresponding to the midpoint of the arch of the circle formed by all the heads of the metatarsal bones.
In simple terms, it is located a little behind the head of the first metatarsal bone.
Even though this concept is more or less known by all the people working in this branch, the problem of how to identify this point on the footwear’s sole in order to align the cleat and consequently the pedal axis, lasts.
Talking about this procedure, the most creative solutions came out.
Actually, the solution is easier than we think. We just have to think about what is available.
The most common mistakes are:
- Measure the position of the cleat starting from the outer perimeter of the footwear. The shoes often have plastic or leather inserts which alter their external dimensions.
- Measure the cleats starting from the base or the tip. The pedal axis of the cleats on the market passes through a point which is differently located in each model.
- Search for the first metatarsal bone with the foot resting on the heel and not with the foot putted on the shoe. If the foot is in avampodalic support, it stiffens and shortens itself.
The correct procedure is:
- Detect the foot’s measurements and, through a simple algorithm, identify the distance from the heel’s balance point;
- Record the distance on the shoe, starting from the inside of the heel of the shoe.
- Identify the passage of the pedal axis on the cleat’s model in use.
- Make the balance point of the foot (located on the footwear’s sole) coincide with the axis of the pedal (located on the cleat).
