Because it is
hidden, some manufacturers make great compromises in the
midsole in order to make their walking
and hiking boots more instantly comfortable and cheaper.
This is often considered a shortcut in production that might
show a reduced performance of the boot.
Scarpa, like
many of the walking boots in our range, uses several midsoles
in its footwear range - the choice being dictated by the
requirements of each of the boots. Each
of the Scarpa midsoles is graded to offer differential flex
characteristics down the length of the boot whilst giving
maximum lateral support.
The midsoles
are also graded by size to ensure constant performance characteristics
in each walking boot size. The method by which midsoles
are attached to the upper is critical to the performance
and durability of the walking boot. Most manufacturers simply
bond or staple the midsole. Scarpa "Blake" sew the upper
and midsole together on all their hill and mountain boots.
Not only does this improve the strength of the boot but
it is critical if ever the boot is to be resoled.
For those more
adventurous hikers and climbers, please bear in mind that
the stiffness of the midsole is also a critical factor if
you plan to use crampons with your boots. See 'Performance
flex', 'Proflex', 'Pro-Fibre' and 'Pro-Flex XT' for more
information on Scarpa midsoles.
