PERFORMANCE AT EVERY PHASE<br />
CONTACT<br />
At the contact phase, runners land with<br />
a force several times their bodyweight,<br />
generating repeated shock and<br />
vibration throughout the foot and body.<br />
The Norvan LD’s midsole is comprised<br />
of an EVA/Polyolefin elastomer blend<br />
that works to mitigate these contact<br />
phase forces and provide noticeable,<br />
lasting comfort over longer distances.<br />
FOOT FLAT<br />
During this phase, the foot pronates<br />
or flattens to provide the body<br />
with a stable base of support.<br />
Key components of the Norvan<br />
LD’s upper and bottom unit work<br />
in concert to comfortably and<br />
confidently hold the foot.<br />
PROPULSION<br />
As a runner takes off from the ground,<br />
their forefoot widens considerably.<br />
The Norvan LD toe box is constructed<br />
to accommodate this expansion for<br />
maximum comfort. Underfoot, the<br />
midsole material is specifically selected<br />
to generate a dynamic toe-off for<br />
efficient propulsion with less effort.
