CloudTec Sphere™
CloudTec® is our proprietary cushioning system, engineering foam to create different running experiences. Developed for our pinnacle racing shoes, CloudTec Sphere™ balances power with comfort, for a fresh leg-advantage when the race heats up.
Who says you can’t engineer fast?
CloudTec Sphere™ is our most dynamic form of CloudTec® – resulting in ultimate speed, responsiveness and everlasting cushioning.
How it works
Thin gaps separate the forefoot, midfoot and heel – allowing the foam to be less constrained and enabling greater compression and expansion.
Superior cushioning
Combined with soft, lightweight pinnacle superfoams, CloudTec Sphere™ delivers long-distance comfort, high energy return and powerful responsiveness.
Improved running efficiency
CloudTec Sphere™ reduces muscular demands and improves running efficiency. This results in a fresh leg advantage around mile 22, where the body starts to slow down, but the race heats up.
Co-created with elite athletes. Refined by feeling.
We partnered with 22 of our elite athletes to bring CloudTec Sphere™ to life, but instead of focusing solely on numbers and data, we asked them to share what they felt. Lighter. Faster. More propulsive. Just right. The result? Our new LightSpray Cloudboom Strike 2.
“I love that I get to be part of that creation process. Testing. Trying. Giving feedback. Because I can feel it.” - Hellen Obiri
