If you’ve spent more than a minute in an airport recently, you might’ve noticed everyone wearing these curved running shoes strapped with weird hole-y outsoles under them. Those ubiquitous sneakers are by a Swiss brand called On Running, and if you don’t already own a pair, you should know that they’re only getting trendier by the second — for practical reasons, actually!

Whether you’re already an On wearer or new to the brand and wanting a good, comfy sneaker, then good news: the popular On Cloudswift 3 is secretly up to 30% off for Labor Day at Nordstrom and On. If you’re not picky about colors, a limited selection is 30% off at Nordstrom (sizes sell out quickly there though, so move fast). For more variety, head to the On website for a still-solid 25% off. Wearers call this style the “most comfortable shoes I ever owned,” even noting they “retired [their] Hoka and ASICS” after getting a pair — so you’ll want to move fast on this deal because it’s a good grab.

This means it has a curved outsole from the heel to toe that easily propels your toe-off when running and walking. In other words, your stride in these should feel like autopilot. The removable memory foam insole cushions your foot and distributes your weight consistently for an upbeat but even step. A durable, high-abrasion rubber tread gives you stability indoors and out, even on wet surfaces. “After tearing a tendon on my foot these are the only shoes I have been able to wear,” one wrote. “Gives me the support I need both on the sides and bottom of my foot.”

Designed with a “sock-fit,” the sneakers boast a connected tongue that keeps your foot in place as you move. “For me, that is a MORE comfy design!” one wrote. “I honestly think the whole soft stretchy surround makes for an incredibly comfy fit. The heel being high at back does NOT give me any discomfort whatsoever.”

They’re especially comfy for leisurely strolls, though some reviewers say they’ve taken their pairs out on 10-mile runs. You can nab a pair in women’s sizes 5-11 and men’s sizes 7-14 with half-sizes.

“Best shoe I’ve purchased in a very very long time. I do not use as a running shoe but as a shoe to walk with multiple leg, knee, hip, back and feet issues. This is my everyday shoe and I couldn’t be happier. I have a narrow foot and this shoe works well. I have no fat pads in my heels and I feel no pain in this shoe. I have bursitis both sides and need two hips I’ve also had a total knee and there was no break in time with my cloudswift….for me. I am very happy with my shoes and now have multiple pairs.” — Kmboseo

“Bought these for my trip Europe. I was planning to doing plenty of walking and hoping to get a few runs in while I was there. These shoes were super comfortable and perfect for the trip. No blisters from thousands of steps every day sure seeing!” — Tnf1

“I bought these sneakers for my work, and they’re fantastic! Super comfortable with great support for long hours on my feet. The grip is solid, and they’re easy to clean. Definitely recommend for anyone working long shifts on their feet!!❤️” — Ferri Hon

“I’ve always worked out and run in Brooks and Saucony but have developed some foot issues. I tried Hoka but don’t love them. I love these shoes. I use them mainly for the gym but have also worn them all day traveling and found them so comfortable. Will continue to buy and wear this shoe.” — Jgk123
