Compare your shoe's insole length to the guide below. To find your insole length, measure your foot and add 1.5cm for a regular fit, 1cm for a snug fit or 2cm for a looser fit.
To measure your foot most accurately, stand on a tape measure with your heel against a wall. While standing up and looking over your foot, read the measurement at the end of your longest toe. Remember to measure both feet and use the measurement of your longer foot. Find out more here.
Compare your foot measurement to the below guide to find your best shoe size. If you are between sizes we recommend going for the larger size.

Built for endurance on rugged technical terrain, with the combination of Helion HF hyperfoam, Missiongrip outsole, and a breathable Leno weave upper, delivering high energy return, plush cushioning, and advanced grip.
The On Cloudultra 3 Men’s Shoes are built for ultra-distance trail missions, keeping you energised through every mile. Featuring a Helion HF hyperfoam dual midsole, this shoe delivers powerful rebound and cushioning, ensuring your legs feel fresher for longer runs. Whether climbing steep switchbacks or descending rocky paths, you’ll experience consistent energy return with every stride. Constructed with a recycled polyester Leno weave upper, this shoe provides abrasion resistance in high-wear zones while maintaining breathability and quick-dry performance. The combination of strength and ventilation means your feet stay protected, cool, and comfortable no matter how harsh the conditions. When the terrain gets technical, the Missiongrip rubber outsole steps in with its Finite Element Analysis (FEA)-engineered lug design, offering superior traction and stability. The new lug geometry bites into rugged surfaces, making it reliable on mud, loose rock, and steep climbs. Combined with the engineered rocker, every step is smoother, more efficient, and built for speed.

Excellent Pair of On Running hiking shoes! Eric, 15 February 2026 Already have a pair of Cloudultra Pro and they blew my mind...hence I wanted to get another pair of the all black Cloudultra 3 for wearing to work. The air ventilation of the shoes are excellent....they are also quite comfortable to wear in although a big less bouncy compared to the cloudultra pros but that's expected! The design is also excellent! I am now a big fan of On Running and highly recommend this product! Make sure you go down half a size for all On Running shoes... Quality: Value for Money: Fit: Fit Tips: Most On Running shoes are recommended to go half size down...they are always half size too big... Overall Rating:
