How On Cloud Shoes Work: CloudTec® Explained, Plus Which On to Buy

Quick answer: On Cloud shoes feel different because of CloudTec®, the hollow "cloud" pods on the bottom of the sole. When your foot lands, the pods squish down and slide back a little. That softens the landing, then the pods firm up so you can push off. The result is a ride that feels soft when you land but firm and fast when you take off.

Most running shoes only cushion the up-and-down impact of each step. But when you walk or run, your foot also pushes forward. On designed CloudTec® to handle both directions at once. That's why On shoes can feel firm and smooth at the same time.

Most running shoes use thick foam to soak up impact. Foam is great at cushioning the up-and-down force of a step. But each step also pushes forward, and solid foam can make that forward motion feel like a quick stop. Some runners feel that as a jolt in their shins.

CloudTec® works differently. Each hollow pod squishes down and shifts slightly forward when it hits the ground. That small shift softens the stop-and-go feeling of each step. Once the pods compress, they lock together into a firm base, and the Speedboard® plate (in models that have one) helps you spring forward.

• Bottom line:

• CloudTec® is like a suspension system for your feet. The pods soften each landing, and the firm base helps you push off without wasting energy.

People often describe On shoes as firm, yet they still feel protective and smooth. That mix is what makes them stand out.

JD Expert Question: "If I rotate between the Cloudmonster and other On models, will the plate and pods keep their bounce after a lot of miles?"

JD Expert Answer: Because the pods do much of the cushioning work, the foam and plate inside don't get crushed as quickly as in some all-foam shoes. That helps the ride feel consistent for longer. Like any running shoe, though, your On pair will wear down over time. Most runners replace their shoes every 300 to 500 miles, or sooner if the cushioning feels flat.

• How they feel:

• On CloudTec®: Feels firm and controlled. You don't sink in. Instead, the pods compress and then spring back.

• Soft super foams: Feel very bouncy and soft. They're great for straight-line speed but can feel less stable on sharp turns or uneven sidewalks.

• How they wear:

• On: The pods rely on shape, not just foam, so they hold up well. Small stones can sometimes get stuck between the pods, so check your soles now and then.

• Foam: Over many miles, foam slowly packs down, which can make an older shoe feel flat.

Who should buy an On Cloud shoe?

On Cloud shoes are a great pick if you want a smooth, stable ride for walking, travel, the gym, or easy runs. If your legs feel heavy after long days on concrete, the soft landing and firm push-off of CloudTec® can help. If you prefer a very soft, sink-in feel, a max-cushion foam shoe may suit you better.

On makes several "Cloud" models. Here's a simple guide to the most popular ones:

• On Cloud 5 or Cloud 6: The everyday classic. Light, easy to slip on, and great for walking, travel, and casual wear.
• On Cloudmonster: The most cushioned. Big pods for a bouncy, soft ride on long walks and runs.
• On Cloudnova: A stylish everyday sneaker with a supportive fit. Great for all-day wear and standing jobs.
• On Cloudsurfer: Soft and smooth for daily runs and easy miles.
• On Cloudrunner: Extra support for runners who want a more stable shoe.

Most people wear their usual size in On shoes. A few tips:

• Between sizes or wide feet: Go up a half size. Some On models have a fitted toe box.
• Running long distances: Leave about a thumb's width at the toe, since feet swell on long runs.
• Coming from Nike or adidas: Most shoppers wear the same size. If Nike running shoes feel snug on you, try a half size up in On.

• Are On Cloud shoes good for walking? Yes. The rocker shape and CloudTec® pods make each step feel smooth, which is why many people wear them for travel and long days on their feet.
• Are On Cloud shoes good for running? Yes, especially for easy runs. For long runs, choose a more cushioned model like the Cloudmonster or Cloudsurfer.
• Why do rocks get stuck in On shoes? The gaps between the pods can trap small stones, especially on gravel. A quick check of your soles after a walk keeps them clear.
