How a SCHÜRR shoe is made

The last is at the beginning of every model development. It defines the later shape of the shoe. When developing a shaft, i.e. the upper part of a shoe, there is a lot of manual work at the beginning. The first samples are made entirely by hand. Only when a model has been convincing in terms of shape and fit the work in CAD begins: the construction of the individual parts, the grading (i.e. the scaling of the models in all sizes that will be available later) and the creation of the necessary data for the punching tools that will later be required for production. It is a long way from the first draft to the certified professional and safety shoe.

 

 

1. Punching

The different parts of the shaft are cut with punching tools. Worked-in slots, spikes and thorns bring clearly indication for later assembly of the shaft parts.

 2. Skiving

To smoothen the edges the thickness of the material is decreased

3. Sewing the upper

The assembly of the upper parts demands high precision.

4. Strobel method

The shaft consisting shaft material and lining gets sewn up flush with the insole. Advantage about this technique is the low weight and the high flexibility. Special feature about SCHÜRR shoes manufactured with strobel method are the integrated gel-parts from the triple cushioning resp. triple cushioning plus in the insole.

5. Lasting

A lasting machine is used to affix the leather upper to the underside of the insole.

6. Surface grinding

After the lasting, the underside of the shaft has to be grinded. Thereby you have to keep attention, that not to much material gets grinded off resp. the gel-parts in the triple cushioning doesn't get damaged.

7. Roughening of the sole

In order to increase the surface and maintain the bond, the inside of the soles is roughened.

8. Marking

The sole edge gets marked on the shaft. This marking has strictly to comply with the adhesive application.

9. Apply the adhesive

The adhesive is applied by hand.

10.Bonding outsole and shaft

The adhesive is activated with heat and then attached manually. Afterwards its pressed by a machine to ensure permanent bonding.
