On March 18, 2015, Hilary Duff was spotted in Studio City, Los Angeles, sporting a bold style transformation that paired high-fashion accessories with classic athletic performance.
While her minty turquoise hair—styled by Amber at 901 Salon—captured the headlines, her choice of functional, everyday footwear remains a masterclass in off-duty celebrity style.

Hilary Duff’s Athleisure Formula: Monochrome Layers and Nike Free 5.0 Trainers
The actress grounded her vibrant hair color with a sleek, monochromatic base—layering a grey biker jacket over a crisp white top and dark leggings for an effortlessly off-duty finish.
Anchoring the look, she chose Nike’s Free 5.0 TR Fit 4 Print trainers, a mid-2010s athleisure staple engineered for movement but embraced for street style.
Designed with Nike’s signature “barefoot-inspired” flexibility, the lightweight cross-trainers—complete with breathable mesh, Flywire support, and articulated flex grooves—offered the perfect balance of performance and polish for a gym-to-errands moment.

She completed the look with a quilted Chanel bag and a takeaway from Joan’s on Third, reinforcing the polished, errand-ready aesthetic that defines her off-duty style—much like her Nike Free Flyknit sneaker moment, where functional footwear meets elevated everyday dressing.

The Nike Free 5.0 TR Fit 4 Today: From Athleisure Staple to Archival Classic
While Hilary Duff’s sneakers perfectly capture the mid-2010s athleisure moment, the Nike Free 5.0 TR Fit 4 is no longer in production. Originally released around 2014, the model has since become a “legacy” silhouette as Nike continues to evolve its Free and Training (TR) lines with newer technologies and updated designs.
Today, the Fit 4 sits firmly in Nike’s archival catalog—remembered for its lightweight construction, flexible sole, and gym-to-street versatility that helped define an entire era of off-duty celebrity style.

Although Nike no longer sells this model, the Free 5.0 TR Fit 4 remains widely available on the secondary market. Resale platforms like Poshmark and Mercari often carry pre-owned pairs, while eBay is one of the best places to find “new old stock”—unworn pairs that have been stored since their original release.
Pricing typically ranges from around $20 to $60, depending on condition, making them an accessible option for those looking to recreate the exact look.

For those who love the balance of flexibility and support that made the Fit 4 so popular, several current Nike models carry that same DNA forward.
The Nike Free Metcon 6 blends the brand’s signature flexible sole with added stability for strength training, making it the closest modern equivalent for gym use. Meanwhile, newer versions of the Nike Free Run 5.0 maintain the “barefoot-inspired” feel but are better suited for casual wear and short runs.
For a more budget-friendly option, the Nike Flex Experience Run 12 offers a similarly lightweight, minimalist design that echoes the comfort and ease of earlier Free models.
