Carrie Underwood may best be known for her iconic hits (who among us hasn’t screamed along to “Before He Cheats?”), but let it be known: the country singer is also a superstar in the gym. From intense arm sets to leg-sculpting squat circuits, she’s proven time and again that she’s a pro on the pullup bar and workout mat. In fact, just last week, Shape’s social media director Marietta Alessi joined Underwood and her trainer, Eve Overland in a bodyweight workout at the BodyArmor #LYTEUpAustin event. And between rounds of high knees and good mornings (in 95-degree weather) she spied the celeb wearing her go-to pair of sneakers, the Adidas x Stella McCartney Ultraboost 20s. (Pssst: These are the best knee compression sleeves according to customer reviews.)

Designed to propel you forward with every step, these ultra-responsive sneakers are made from an adaptive knit that contours to the shape of your foot. Lined with plush cushioning, these shoes protect your knees, ankles, and hips from the impact of high-intensity workouts — like running and HIIT — and return that energy, adding extra bounce to each movement.

A long-time wearer of the Ultraboosts, Underwood previously told Shape that she originally bought the shoes on Amazon while looking for a joint-supportive sneaker. “I have knee problems, and I’ve been looking for shoes for years that don’t make my knees hurt,” she noted, adding that these sneakers have been “the most comfortable shoes” for her knees — and she’s not alone.

“[They] were totally comfortable and [the] fit was perfect,” wrote one Nordstrom shopper, who tested these sneakers in a kickboxing class. An Adidas shopper commented that they can walk seven to 10 miles in these kicks and swears they’re “always comfortable.” Another agreed that they “loved these the minute [they] put them on,” and a third said they’re “perfect for a full day on your feet.” (BTW: One Shape editor swears by these cross-training sneakers for knee pain.)
