:Technology · Upper materials
 

The main body of the boot can be leather, fabric, suede and, thanks today's technology also Kevlar, carbon or synthetic coated materials.
A one piece upper construction has no unnecessary seams or stitching and is therefore the most waterproof.
The different thickness of the upper material gives a different degree of rigidity in the construction. The upper should be waterproof but also ensure good breathability.

To learn more about leather...


Full grain leather

Is a full grain water repellent Leather. This is the best quality and the toughest and most water resistant but it also has breathable characteristics and is approved by all main manufacturers of breathable and waterproofing inter layers. This leather is chrome tanned and re-tanned with synthetic products for a warmer smoother and natural feeling. The leather is waterproofed during the tanning process and is drum dyed all through its' thickness.
Nubuck leather

Is a full grain water repellent leather that has been buffed to give it a velvety finish. It is hard wearing and attractive looking, the open structure allows shoe conditioners to be absorbed properly. This leather is water resistant but it also has breathable characteristics and is approved by all main manufacturers of breathable and waterproofing membranes. The leather is waterproofed during the tanning process and is drum dyed throughout its' thickness. Available also in waxed version.
Suede leather

Is leather made from the flesh split of the hide and is finished with a velvety nap. This type of leather is made water resistant but the performance can not be compared with the high standards of a full grain water repellent leather. Special treatment renders suede oil and water repellent and stain proof. Suede is high quality leather and an excellent upper material for trekking boots where lightness, flexibility and softness are required.
PU coated leather

Leather made from the inner splits of the hide finished with a polyurethane coating. This leather is made resistant to water penetration and has also a high resistance to scratches. There are many different types of PU coated leather depending upon the technical standards they are required to reach. The coating can be embossed with a design giving to the leather the most wide variety of textures.
