Introduction: Why Fit Matters for On Cloud Shoes
On Cloud shoes are known for their lightweight construction, innovative cushioning, and sleek style — but none of that matters if the fit isn’t right. A proper fit enhances comfort, prevents injury, and ensures you get the most out of the CloudTec® technology. Whether you’re a runner, walker, or casual wearer, this guide will help you confidently choose the right size for your On Cloud shoes.
Do On Cloud Shoes Run True to Size?
Generally, On Cloud shoes run true to size, but there are a few exceptions depending on the model and your foot shape. Most wearers find that their usual running shoe size works well, though some runners with wider feet may prefer going half a size up for added comfort — especially in more performance-focused designs like the Cloudflow or Cloudboom.

Common Fit FAQs
Do On Cloud shoes stretch over time?
A little. The mesh upper may adapt slightly to your foot, but don’t rely on stretch for comfort — choose the correct size up front.
Can I wear On Cloud shoes if I have wide feet?
Yes, but you may need to size up, or choose models like the Cloudmonster or Cloudrunner which offer more room.
Should I size up for long-distance running?
If you plan to use On shoes for long runs or marathons, consider going half a size up to accommodate swelling and avoid toe crowding.
Final Thoughts: Choosing the Best Size for Your Needs
On Cloud shoes deliver performance and comfort — but only if they fit well. Stick to your normal athletic shoe size for most models, and consider half-sizing up if you have wide feet or prefer a looser fit. When in doubt, try them on in-store or order from a retailer with a flexible return policy. A perfect fit ensures you’ll enjoy every step on the clouds.
