One thing that Paraboot is well-known for is their choice of construction method. Paraboot uses Norwegian construction method for most of their shoes and boots they make.
So what is Norwegian construction method or Norwegian welt? Norwegian construction method is known to be durable and also be waterproof. Generally, we won’t be able to tell much from normal usage compare to Goodyear welt.
Here is an of explanation from Paraboot.com.
“Principle
The upper is fixed to the sole by means of a welt. Both lines of stitches are visible: the “Norwegian” welt connects the welt to the upper and the assembly insole. Special fine stitching connects the welt to the outsole. It is also possible not to have a welt, in which case the two lines of stitches are sewn directly onto the leather at the bottom of the upper; this serves as a welt.
History
The Norwegian welt was particularly used for mountain and work shoes. Nowadays, it’s also used for casual shoes. For the record, the origin of the name remains a mystery but has no connection with Norway.
Advantages
This solid and flexible mounting technique both makes the shoe waterproof and resoleable. In addition, the Norwegian welt creates an assumed sportswear look. From a purely technical point of view, the advantages of the Norwegian welt are comparable to those of the Goodyear welt.”
