PORON is a microporous polyurethane foam which
is able to cushion effectively the 'stepshock' of walking and running.
Its open cell structure gives the material the ability to absorb a measure
of the moisture vapour generated by the active foot.
The highest degree of shock absorption
More shock absorption in the insole means less shock to feet and joints.
And no other insole materials offer more shock absorption than PORON
cellular urethanes. In side-by-side drop weight tests, PORON materials
outperformed vinyl sponge, neoprene sponge, sponge rubber, latex foam
and solid viscoelastic. Which is why PORON materials offer the
best cushion against impact.

Maximum retention of comfort and flexibility
PORON urethanes are made without plasticizers, which means
the insole won't shrink or become brittle and crack with age. PORON
urethane insoles retain "like-new" softness and flexibility,
resisting the tendency of other insole materials to bottom out and take
a permanent compression set. This results in maximum comfort for the
life of the shoe.
A breathable layer to help feet stay dry and cool
Insoles made with PORON urethane material form permeable
layers that draw water vapour and perspiration away from the foot, helping
to keep shoes and feet dry, while reducing foot odour.
It all adds up to performance
Superior performance in just about every conceivable category,
and resistance to abrasion, friction, tension, and stitch stress. PORON
urethanes are lightweight, smooth to the touch, and resist piping, for
the greatest degree of shoe comfort, over the greatest length of time.

A PORON insole for every kind of shoe
The PORON material product line offers a
wide variety of colors, thicknesses, densities and surface textures
to accommodate any kind of shoe for almost any activity - from the everyday
wear associated with dress shoes, to the rigorous demands placed on
shoes worn during high-impact sports and exercise. And if the precise
PORON material doesn't already exist, one can be custom formulated
for the needs of a specific insole, shoe, activity or manufacturer's
physical and aesthetic requirements. Contact us for further details.
