TWICE’s Nayeon is well known for many things, including her music, but her personal style is severely underrated.

The K-pop star’s looks are often a mix of feminine and comfortable pieces, often pulling inspo from Y2K aesthetics. The “ABCD” singer favors bright colors, playful textures and silhouettes that flatter her frame. In short, we trust her taste, and clearly so does Vivaia, an eco-friendly footwear brand founded in 2020. The retailer tapped the K-pop act to star in its spring 2026 collection titled Feel the Comfort.

The girl group member modeled some of her favorite styles, which consisted mostly of Mary Jane-meets-ballet-flat styles and whimsical sneakers in various colors with feminine and edgy touches. In specific, Nayeon wore the brand’s Square-Toe Jogger Sneakerina retailing for $159, the Square-Toe Hybrid Mesh Mary Janes retailing for $149, the Square-Toe Margot™ Mary Jane 3.0 retailing for $139 and the Mesh Floral Square-Toe Mary Janes for $149. You can shop her picks below and on Vivaia’s website.

When asked, “What does comfort mean to you?” Nayeon responded in a statement saying, “When I am being my true self.” One of our favorite styles is the Square-Toe Hybrid Mesh Mary Janes in a tan hue with red accents. The shoe features all-round mesh paneling, making them breathable, along with dainty lace-up closures and a playful bubble sole. This style also comes with interchangeable red laces, which Nayeon chose for the campaign, along with floral charms in matching hues that can be attached to your laces to change things up. Sizing is available from 5 through 9.

Another great option is the Mesh Floral Square-Toe Mary Janes that feature see-through mesh throughout and floral accents. Fun fact: The mesh uppers are made with recycled plastic bottles. The shoe has gold clasps to adjust the fit and square toes that Vivaia seems to incorporate in a bunch of its shoe creations. Again, this silhouette is see-through, but you can wear socks with them, which could be a fun stylistic choice if you don a fun print or color.

All of Vivaia’s footwear focuses on on-trend silhouettes with an emphasis on comfort. The brand’s mission of comfort meets style came from a singular question: “Why can’t heels, and all women’s shoes, have a sneaker-like comfort?” Each of its shoes is equipped with padded insoles to provide ultimate comfort. The retailer even has wide-foot-friendly designs, creating a more inclusive range for people to shop.
