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.

For long trail runs, off-road training, ultra distances
Upper
Speedboard
Outsole
For the ultimate ultra-shoe, we’ve doubled up on Helion™ superfoam. Two layers of Clouds work in tandem to provide ultimate cushioning and long term comfort.
The all-new FlipRelease tool makes finding a more comfortable fit as easy as flicking a switch. Ideal for long distance running when feet can swell.
The two-layer sandwich mesh upper is durable and breathable. Along with the wrap-fit construction, perforated for superior climate-control, it fits like your favorite socks.
Connected Clouds keep stones out and are easy to clean. Missiongrip™ with three independent traction patterns let you master mixed terrain on and off the road.
On models are straight forward. In most cases, you just take the same size as your current shoes.
