The level of rigidity of a boot depends mainly on its midsole.

We use six different Bestflex midsoles made from different materials, giving our boots five different levels of rigidity and flexibility, each ideal for its intended use.

The midsoles marked with a ‘+ P®’ are aditionally lined with PORON® Performance, which gives the boot a high energy return and excellent impact absorption for the complete life of the boo (for more information, see: PORON® Performance)

Bestflex 5 / Norwegian welt

A special midsole used in boots made according the traditional system of Norwegian stitching (twin seem stitching). It is a rigid sole, but with a certain degree of flexibility. The proper system of double seem stitching reinforces the rigidity of the boot.
