Which aspect of market dynamics poses a potential risk for retailers of fitness apparel?

The strategies of direct-to-consumer brands represent a significant risk for retailers of fitness apparel due to their ability to disrupt traditional retail models. Direct-to-consumer brands typically eliminate the middleman, which allows them to offer products at lower prices and often enhance the customer experience through personalized marketing and more direct engagement with their consumers. This shift forces traditional retailers to adapt quickly to maintain their customer base and margins. The growing preference for shopping directly from brands can lead to reduced foot traffic in brick-and-mortar stores, affecting sales and profitability for those retailers who rely on more traditional distribution channels.

While other factors like technological advancements and changes in customer preferences are important considerations, they may not pose as direct a threat as the rising effectiveness and appeal of direct-to-consumer brands, which have a tangible impact on competitive positioning within the market.
