Quality guide


Bond strength

Since SAWA shoes feature cemented and stitched sole. The bonding is considered as total. The sole stitching is made with a nylon waterproof thread.

Flexing resistance

The shoe is folded at 90 degrees to define the flexion point of the sole. A notch is done at the flexion point. Then the shoe is flexed 30 000 times. After this test, we observe if the notch has increased. As far as SAWA shoes are concerned, the notch did not increase at all, which prove that SAWA shoes resist to flexion.




The sole of the shoe is scraped against a 40 meters abrasive band. A good quality sole loses 250 mm3 volume after this test. As far as SAWA soles are concerned, they just lose 79 mm3 volume, which proves that SAWA sole resist to abrasion 3 times more than a good quality sole.


Tear Strength : Several perforations are done on the upper of the shoe. A pressure is applied on the perforations until they widen. In the shoe industry perforations start widening under a 3.5 deca newton pressure. As far as SAWA shoes are concerned a 7.6 deca newton pressure is needed to start widening the perforations, which proves that SAWA shoes resist to tear strength 2 times more than the average.
