On Cloud Ultra Iceberg & Glacier
£160.00 £130.00
The Cloudultra in Iceberg and Glacier stays fully tonal in cool sage and light grey from the mesh upper down through the midsole, with white On Running text and a tonal On logo on the side providing the only graphic detail against the muted palette. The low-profile CloudTec midsole with its trail-ready lug pods sits close to the ground for a stable, planted feel that handles technical terrain with confidence across long distances. Calm in color, serious about the miles ahead.
On Cloud Shoes Size Guide
On Cloud trainers use standard On sizing and most styles fit true to size, so we recommend ordering your usual UK size. If you are between sizes, or looking at a chunkier model like the Cloudmonster or Cloud 5, we suggest going up half a size for extra room in the toe.

How to Measure Your Foot
Place a sheet of paper on the floor against a wall. Stand on it with your heel touching the wall. Mark the tip of your longest toe, then measure from the wall to the mark in centimetres. Match that number to the Foot Length column above. If you land between two sizes, choose the larger one.
Fit Notes
On Cloud shoes fit true to length but can feel slightly narrow in the toe box. If you have wider feet, some models such as the Cloudrunner, Cloudsurfer and Cloudgo come in a Wide fit. Measure both feet and use the larger measurement, since most people have one foot slightly bigger than the other.
