SOFTER & MORE ENERGY RETURNThought the Nike LunarEpic Low Flyknit 2 was
soft? It was. Thought the Nike Epic React was
even softer? You bet—11% softer to be exact.
Along with being significantly softer than the
LunarEpic’s Lunarlon foam, the Nike React foam
also managed to be 13% bouncier. The Nike Epic
React 2 (shown at the top of the page) is the
latest running shoe to feature the foam.
LIGHTERNike Epic React is 5% lighter than the
LunarEpic Low Flyknit 2—making it one
of the lightest incredibly-cushioned
shoes you can buy.
MORE DURABLEWe gave our testers React shoes that had
been worn for at least 500 miles, and sent
them on a run. When they returned, we
asked them how many miles they thought
the shoes had on them. The highest answer
was 100. The lowest was “brand-new.”
And the average was around 15 miles.
That’s what we call durable.
DEVELOPING THE FOAMHow we invented a new recipe
for softer, springier, lighter and
more durable cushioning.
The best innovations come from
listening to the voice of the athlete.
When we asked athletes what we
could improve in cushioning, their
answer was simple: everything.
And we were up to the challenge.
Nike chemists spent three years
testing new materials and design
methods. After 400 combinations,
we finally landed on Nike React.
SO YOU HAVE THIS INCREDIBLE NEW
CHEMISTRY, AMPLIFIED WITH THIS
FLUID GEOMETRY THAT WE JUST NEVER
HAD ACCESS TO BEFORE. THAT’S WHAT
MAKES NIKE REACT SO UNIQUE”
Design Innovation Director, Nike
Powered by heat map data from the
Nike Sports Research Lab, designers
determined exactly how much Nike
React was needed and where.
To shape the proprietary foam into footwear,
Nike designers looked again to the athletes
—how they move, in which direction, and with
how much speed and force.
Using computational design —
mathematical formulas to create a
fluid geometry — designers shaped
the sole, matching athlete data to
