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 AW
Brand:On Running
Code:312.00069 W
Technology: Remove reasons for turning back with the Mid Sock. It’s all about balance. Lightweight and breathable, yet snug with subtle support. Technical mesh to regulate temperature. All in a sock just high enough for a feeling of both protection and performance. So you’ll want to extend your run. Materials: On Performance Socks combine a polyamide and elastane blend with technical mesh paneling. The mesh sections help keep foot temperature in perfect balance. Cooling when things heat up, warm enough that you won't get cold feet - whatever you're about to take on. Design: Your running sock might not win you the race, but it could lose you one if it doesn't perform. That's why we set out to see how much performance we could put into a running sock. Turns out, a lot. Like the pattern at the arch which triggers sensory receptors to prime your feet for the run. Plus Swiss Engineering to then keep the sock firmly in place. For performance standards that don't slip.
On models are straight forward. In most cases, you just take the same size as your current shoes.
