Damping and Dynamics –perfectly matchingGetzner g-sole is the innovative
solution for insoles and midsoles. It
is made of PU (polyurethane) and isideal for applications in the medical,leisure and sporting sectors.
he combination of an outer soleand insole or midsole with g-soleensures comfort and provides all thestability and support the foot requires.
The interplay between damping anddynamics is perfectly balanced in bothversions. Constant long-term elasticity and a high capacity for recovery ensure its effectiveness across the entire life span of the shoe in which it isfitted without any loss of comfort. This
makes g-sole suitable for use in customised soles, too – be it for medical or
sporting applications.

TBe on the safe side with g-soleg-sole is designed and manufacturedin Austria. In addition to its uniqueproduct properties, g-sole scores extra points for its short delivery routes
within Europe. Due to state-of-the-art
storage, individual materials can be delivered at short notice. This means thatdelivery times can be carefully planned,
ensuring a reliable and punctual service. Last but by no means least, service is a top priority at Getzner and ourteam is always on hand when you needsupport.

Skin friendly
All g-sole products
have been dermatologically tested and approved for skin compatibility. They fulfil
the requirements of Regulation (EU)2017/745 (MDR) with regard to harmful
substances and are suitable for medical applications in orthopaedics. Directskin contact is harmless even over alonger period of time.

Added value:– Produced in Austria for quick andreliable availability of goods– Sustainability in practice in a
family company– Ongoing innovation to meetgrowing market demands– Personalised service for individual customer requirements

Selected g-sole materials
are open-cell, which ensures better breathability.

We are very satisﬁed with the consistently highquality of the Getzner foams. Short delivery
times and exceptional communication make thisthe perfect solution for us.

g-sole range of use
The g-sole product portfolio contains a range of six
foams, which are suitable for use in the medical, recreation and performance sectors.

MEDICALg-sole Medical help ensure shoes are
comfortable to wear and provide stability. The foot is optimally cushioned,guided and relieved.
– Comfortable to wear with a light and,if required, thin material– Supports stability and balance– Increased damping protects joints– Retains its shape even with a continuous compressive loadRECREATION

g-sole Recreation provides the perfectbalance between comfort and dynamic
support for recreational use.
– Durable and reliable– Helps ensure shoes are comfortable
to wear– Abrasion-resistant andtemperature-insensitive– Economic

PERFORMANCE

g-sole Performance provides optimal
support during sporting activities. Itsdistinctive dynamic behaviour fulfils
the highest requirements.
– High energy return for greater
performance in sports– Protects against overload underhigh stress– Consistent performance over thelong term thanks to low material

Polyurethane products
for the shoe industry

g-sole is a polyurethane (PU) product used in insoles and midsoles
to achieve the best possible damping
or enhanced dynamics as required.
It is extremely durable and ensuresconsistent performance over the entire lifespan of a shoe.

Unique product properties of g-sole:– Lasting long-term elasticity– High capacity for recovery– Outstanding damping characteristics– Unrestricted life span

g-sole portfolio
g-sole products are classified into threedifferent segments according to theirproperties. Products with pronounced
damping are found in the Medical
segment. Those featuring particularly

dynamic properties are placed in thePerformance segment. Any products
displaying both of these properties fallwithin the Recreation segment.
