With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.
Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!
With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.
So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.
Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.
The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.
Season:2018 SS
Brand:On Running
Code:20.4301 W
Welcome to zero gravity — engineering for those on a mission. The Cloud X is the result of what happens when you take the sole of the Cloud and remix it for athletes who don’t define themselves by any one sport, or any one type of workout. Soft landings. Explosive take-offs. A knit-weave on top and a speed-heel-cap to keep your heel on lock. Make no mistake, this is the lightest fully cushioned running shoe the world, your gym, and your feet have ever seen. All you have to do is get out and mix it up.
Elastic performance laces make for a fast step-in.
Reflective details ensure night visibility.
Functional engineered mesh and adaptive first layer sock ensure comfort no matter how you work out.
A new Speedboard transforms energy into forward motion.
Zero-Gravity foam offers improved performance while also giving you an even greater experience of our signature CloudTec® cushioned landing.
Advanced abrasion pads ensure superior grip and longevity.
Dual-density sockliner, seamless tongue and inner sock provide next-level foot comfort.
The lean heel cap with precision-molded cushion pads ensures your heel is always firmly in place.
Heel to toe offset 6mm
