Nike's warning on Thursday of layoffs next year, delivered alongside a first-quarter sales miss, sent its shares down 6.6 percent to $32.84 in late morning trading Friday — and pulled much of the footwear sector down with it on a day when equity markets were otherwise mostly positive.

The market read matters for sourcing and supply-chain professionals: Nike's top line shortfall and planned headcount reductions signal softer order books ahead, and vendors across the athletic and casual footwear space felt the effect in their valuations. Investors treated the Beaverton-based giant's warning not as an isolated execution problem but as a data point on channel demand for the whole category.

Among Nike's main competitors, the reaction was mixed. Adidas gained 0.8 percent to $81.25, while Puma closed unchanged at $2.46.

The broader brand roster told a more cautious story. Amer Sports fell 0.5 percent to $26.94, Asics slipped 0.1 percent to $26.45, and Birkenstock dropped 0.2 percent to $32.92. Caleres Inc. was down 2.7 percent to $12.97 — one of the steeper brand declines of the session. Crocs Inc. slid 0.2 percent to $119.22, and Deckers Outdoor Corp. fell 1.4 percent to $78.45.

Wholesale-linked names also took hits. Genesco inched down 0.3 percent to $34.72. Rocky Brands slid 0.5 percent to $45.78, Steven Madden Ltd. lost 0.5 percent to $45.48, and Wolverine Worldwide eased 0.1 percent to $19.23. Under Armour slipped 0.1 percent to $4.53.

VF Corp., parent of Vans and Timberland — two brands already under margin pressure — fell 2.5 percent to $14.05, among the sharpest declines among apparel-footwear conglomerates. Lululemon, which straddles athletic apparel and footwear, saw its shares fall 2 percent to $93.92.

Retail told a split story. Shoe Station Group Inc. dropped 3.1 percent to $12.30, the worst performer in the group. Designer Brands Inc. fell 1.7 percent to $5.96, and JD Sports slipped 2.2 percent to $79.50. Yet several big-box and sporting goods retailers moved against the tide: Academy Sports + Outdoors rose 2.5 percent to $49.06, Boot Barn inched up 0.9 percent to $121.09, and Dick's Sporting Goods gained 2 percent to $135.46.

For sourcing teams, the divergence is worth noting. The sellers of branded footwear with heavy Nike-adjacent exposure moved lower, while diversified sporting goods retailers with broader category mixes moved higher — suggesting investors distinguish between brands facing demand risk and retail channels that can flex their vendor mix.

The layoffs flagged for next year remain an announced intention at this stage, with no headcount figures or timeline disclosed in the report. What is confirmed: a first-quarter sales miss, a 6.6 percent single-session share decline, and broad downward pressure across listed footwear names.

How Nike's order patterns and factory allocations adjust in the coming quarters will determine whether Friday's sell-off marks a category-wide correction or a repricing of one company's execution.
