This
traditional type of construction, also called
Zwiegenäht, Roccia, Epler or Norwegian
, is a guarantee for a long life for most heavy
mountain styles. The heavy upper leather is
stitched together with the special insole through
a first stitching (Norwegian type). A second
stitching holds together the midsole. The flex
control is improved by a steel or carbon shank
incorporated in the midsole in this way no additional
thickness of the sole unit is necessary. Stitchings
are not always visible as a rubber rand may
cover them.
Ideal
A
traditional construction is represented by Ideal
stitching, which can be single or double. The
upper is stitched together with the midsole by
a vertical stitching. The insole is not sewn in
as with Goodyear stitching. On traditional styles
this produces very good results and has the advantage
of making the boots easy to resole. A medium flex
of the midsole is obtained by using a reinforced
leather midsole.
Trekking
Ago
An
innovative construction method that combines the
usual “scatola-box” method with the
application of a rubber rand that improves the lateral
protection. The choice of soles is very wide and
it is possible to combine traditional sole patterns
with specially developed rubber body which results
in a sole unit that offers the advantages of a rubber
rand and the ability to resole the boots easily.
Ago
A
very common construction method that has the main
application on light trekking boots and mountain
bike shoes. The upper is folded internally and nailed
to the midsole which is then glued together to the
outsole. It is still a method that uses a last and
allows style which offers protection and stiffness
to the uppers.
Strobel
- Comfort
This
construction finds wide application at the more
economical end of the trekking styles and is achieved
by stitching the insole together with the upper
and glueing this “sock” to the outsole.
This results in a very light and flexible boot
but the negative side is in a poor torsional stability
and flex. For the casual user it has the benefits
of having a level of comfort more akin to a street
shoe than to a mountain boot.
