The Bergler UOS has an upper made of high-quality Perwanger split leather. For perfect comfort and a pleasant feel, it has a soft leather lining, and a cuff and tongue made of fine nubuck. Underfoot, the Vibram® Tessin wedge sole has a rugged profile to ensure good grip and traction. The same as all HANWAG genuine double-stitched boots, it is particularly long lasting and sustainable due to its extremely robust, stable, and repairable construction – and is also fully resoleable.
