With our rubber sole, you do not need to worry about harmful environmental influences. Whether you are at a fuel station or in a workshop, our rubber is extremely resistant and will not disintegrate. Therefore, there are no restrictions in daily use and no reason for you to worry about these little trivialities.
The sole is affixed with a solvent-free, water-based adhesive and then sewn by hand onto the upper. A seam is a sign of craftsmanship and is much more durable than a pure bond.
The ideal sole is always a compromise between flexibility, grip and wear and tear. Also, during design and manufacturing, we cannot recreate perpetual motion. So, the essence of barefoot shoes is having the thinnest possible sole to guarantee the maximum mobility.
Our rubber sole has one of the lowest abrasion factors in the industry. We are particularly proud of this and many publications bear testimony. Martin Mueller, for example, who ran from Gibraltar to Nordkapp, says about our sole: "The sole have has any signs of wear, despite its thin construction. Even after long stretches over asphalt, there are no visible signs of wear and tear."
So, you can be sure that a ZAQQ sole gives you one of the most advanced and durable soles on the market for barefoot shoes.
A shoe is made of many seams, not just the sole seam. A seam always requires a perforation in the material where the thread passes through. However, the big advantage of rubber is that the perforations in the sole immediately close again. In addition, we use polyamide as a yarn type, which does not transmit moisture. So, you do not have to worry about getting wet feet through the seams in our soles.
On the contrary, with non-sewn shoes, the adhesive often softens due to moisture. You can see that when you look at "normal" shoes in the seam area. Often, after just a few weeks, the sole comes away from the upper.
