If you’ve been scrolling through fitness feeds or walking down city streets lately, you’ve probably seen them—cloud shoes. These ultra-light, cushioned sneakers promise a walk-on-air experience, but what’s the real story behind the hype?
What Are Cloud Shoes and Why Are They So Popular?
Cloud shoes have taken the athletic and lifestyle footwear world by storm. Marketed as the ultimate fusion of comfort, style, and innovation, these shoes are designed to mimic the sensation of walking on clouds—hence the name. Originally popularized by brands like On Running, the term ‘cloud shoes’ has evolved into a category of its own, representing a new era in sneaker technology.
The Origin of the Cloud Shoe Phenomenon
The concept of cloud shoes began in Switzerland in 2010 when three runners founded On Running with a mission to revolutionize running footwear. Their breakthrough came with the patented ‘CloudTec’ sole technology—a system of hollow, flexible pods on the outsole that compress on impact and firm up for push-off. This design delivers a soft landing and explosive take-off, creating a sensation runners describe as ‘running on clouds.’
- Founded in Zurich, Switzerland, by Olivier Bernhard, David Allemann, and Caspar Coppetti.
- First launched at the Berlin Marathon in 2012.
- Rapidly gained traction among elite athletes and casual wearers alike.
Today, On Running is a global brand valued at over $5 billion, with cloud shoes at the heart of its success. The brand’s commitment to Swiss engineering and sustainable innovation has set it apart in a crowded market. For more on their origin story, visit On Running’s official website.
How Cloud Shoes Differ from Traditional Sneakers
Traditional running shoes often rely on thick, dense foam midsoles (like EVA or PU) to absorb shock. While effective, these materials can add weight and lose responsiveness over time. Cloud shoes, in contrast, use dynamic cushioning systems that adapt to your stride.
- Weight: Cloud shoes are significantly lighter due to hollow pod structures and advanced materials.
- Responsiveness: The CloudTec system provides immediate energy return, unlike foam that compresses and slowly rebounds.
- Design: Minimalist aesthetics with functional engineering appeal to both athletes and fashion-conscious consumers.
“We didn’t want to make another running shoe. We wanted to reinvent how running feels.” — Olivier Bernhard, Co-Founder of On Running
The Science Behind Cloud Shoes: How Do They Work?
The magic of cloud shoes lies in their biomechanical engineering. These shoes are not just about softness—they’re about intelligent impact absorption and propulsion. Let’s break down the technology that makes walking or running in cloud shoes feel so effortless.
CloudTec: The Heart of the Cloud Shoe
CloudTec is the proprietary sole technology developed by On Running. It consists of individual cloud elements—hollow, flexible cells made from a high-grade thermoplastic—arranged in a precise pattern on the outsole.
- Upon heel strike, the clouds collapse vertically to absorb impact.
- As the foot rolls forward, the clouds lock into place, creating a firm platform for push-off.
- This dual-phase system reduces joint stress while enhancing forward momentum.
Independent studies have shown that CloudTec reduces impact forces by up to 30% compared to traditional EVA midsoles. This makes cloud shoes particularly appealing for runners with knee or joint concerns. For a deeper dive into the biomechanics, check out research published by the National Center for Biotechnology Information.
Helion Superfoam: The Next-Gen Midsole
Beyond the outsole, cloud shoes use Helion™ superfoam in the midsole—a proprietary compound developed by On Running. This material is lighter, more durable, and more responsive than conventional foams.
- Retains elasticity even in cold temperatures.
- Resists compression set (doesn’t flatten over time).
- Delivers a snappy, energetic feel with every step.
The combination of CloudTec and Helion creates a synergistic effect: impact is absorbed efficiently, and energy is returned dynamically. This is why many wearers report feeling less fatigue during long walks or runs.
