Details The On-Running women's Cloudstratus' dual Cloudtec® system is Swiss engineered for maximum cushioning and distance. The lower layer softens every foot strike, collapsing ready to rebound forwards. The upper layer absorbs residual impact and adds even more propulsion. Details like the anatomically engineered upper, the star-lacing system, and ribbed sock liner make the Cloudstratus ideal for runners that demand more: more clouds, more cushioning, more run. Upper Asymmetrical Upper - The anatomically engineered mesh upper is made asymmetrical with movement in mind. Soft and strong, optimized for comfort and breathable for airflow. The star-lacing configuration recruits more mesh from the shoe's flank, wrapping the foot for a secure fit and supporting your natural motion. Where your foot flexes, the shoe flexes too. Anatomically oriented lacing system - With the Cloudstratus the laces are a star feature. The anatomically oriented lacing system creates a star-shaped configuration for increased forefoot control. Doubling up on eyelets offers additional customization options. Midsole Wider surface area and specially designed "Clouds" in the rear-foot help avoid an inward rotation and allow for a stable, yet natural transition. Outsole CloudTec® delivers the ultimate cushioning experience. But at On they always demand more. So they asked, what happens if cushioning is doubled up? The Cloudstratus is what happens. Double layers of CloudTec® mean more clouds, more performance, more run. The Cloudstratus delivers maximum cushioning but stays responsive. It offers additional support that doesn't stifle speed. So you'll want to go twice as far. Heel V-molded heel cap and luxurious memory foam provide a snug heel fit and support the ankle during landing. Forefoot Dual CloudTec® layers - For the first time, two layers of Helion™-enriched CloudTec® work sequentially for enhanced vertical and horizontal cushioning. Connected forefoot Cloud elements distribute pressure as your foot lands, then supports a powerful push off as the Speedboard™ drives you forwards. Less impact, more running.
