Inside of immaterial

2 Jul 2019

we tend not to discuss about the fitting.

Because the fitting is highly depended on personal experiences and foot shape but all the choices we make have a rational reason.

In the architecture realm, as we draw a plan, it is an obvious virtue to have a concrete reason for every single line we place. Like this, all the decision makings is followed by an elaborate reason.

we never chase a value because we feel like it. we learned not to do that.

Generally, the selectable conditions inside of a shoe are materials, forms, insoles. These three conditions are the core values of the interior.

In terms of materials, if we choose to use fabric, it will be great for absorbing moistures but it will suffer from discharging. Furthermore, the fabric becomes a cause of smell for the one who gets easily sweats. Endurance is another issue for the fabric. Leather recovers through time but the fabric is especially weak for the continuous friction. It can easily be penetrated by such force.

All of the shoes that we produce use of calf leathers. The calf leather is softer and thinner but sturdier than cow leather. The calf has small pores too. Through these for the lining, we carefully choose material considering texture on foot and even endurance.


Form or Shape is greatly depended on the person. Generally, the lasts determine the form of the shoes. Of course, special cases like safety boots, sports shoes and etc. are different but most cases, the design defines the form. Therefore, if the shoes are not personalized for a specific person, the form or shape is there for the design.

The last but not the least. The insole.

Each individual’s foot width and instep is highly different but the way foot settles within the shoes is something that we can control. At this moment, the thickness of the heel is the most influential aspect. The heel affects the tension of muscles and ligaments while the person is sitting and standing. About 10 degrees is the angle that minimizes the level of tension.


The calculation “(foot length mm - 70 mm) x tan10 = the optimal heel height”

Through this calculation, it offers about 30 - 40mm, 3 - 4cm 

This is why all the sneakers we produce have 10 degrees inner angle with a 3.5cm heel.

Often people think soft shoes are comfortable shoes.

Yes. soft shoes are comfortable.


But this applies before you stand and walk. When you stand and walk, our weight is on shoes. When the load is momentarily put on the shoes, the insole is turned off and the whole body is turned down at the same time. When this happens, the balance is broken when the insole is raised up and the weight is pressed down. To correct this imbalance, the legs are stressed.

So that our insole is relatively firm. This stiffness is only to support the weight of a person standing and it is soft enough only to support the force on heels and knees while a person walking.
