When these things described above are in order, it is worth remembering that all the outer shells of the monos can be customized up to 30 mm on each side of the outer shell.
Today, mono plastics really differ a lot between different manufacturers, so modifying them requires really high precision / the right tools and craftsmanship.
Nowadays, milling is impossible to use at any stage in the design of the outer shoe because it is simply not possible because they are so thin.
Many stores also often recommend shaped boys as additional sales, but they have very little effect, at least in improving fit.
Many stores also offer “oven” boots / insoles, which, however, are marginal.
In the case of an inner shoe, “firing” helps to detect pressure points that often lead to the shaping of the outer shoe
In the case of the outer shoe, “firing” is very rarely useful because they return to their former shape when they cool down and the heating of the entire shell is completely unnecessary because usually the necessary additional modifications are made to small areas of the pressure house
