Step One's All-New Socks Collection Sold Out Within a Day

— November 18, 2025 — Fashion
Australian underwear brand Step One is stepping into a new category with its first-ever sock collection—and early demand suggests the expansion is already resonating with customers. The brand launched three silhouettes—crew, ankle, and no-show—available in classic black and white. Within the first day of release, both the crew and ankle options reportedly sold out, prompting the company to fast-track restocks scheduled to arrive later this week.

This foray into socks marks the latest chapter in Step One’s broader strategy to diversify its product lineup. In recent months, the brand has expanded into additional categories, including the menstrual-care space.

“The introduction of bralettes and expansion into adjacent categories reflects our ambition to become a more significant part of our customers' everyday wardrobe choices, not just their underwear drawer,” Gallop said.
