(Reuters) - Shares in JD Sports and Puma fell as much as 6.6% and 3% respectively on Friday, while Adidas briefly rose over 1.5%, after U.S. peer Nike ( NKE ) on Thursday forecast a surprise fall in fiscal 2025 revenue.

"Nike ( NKE ) will be busy with recalibrating its business until at least spring 2025, which provides Adidas with excellent opportunity to gain market share," analysts at Kepler Cheuvreux wrote in a note to clients

Nike ( NKE ) was hurt by faltering demand for its sneakers as consumers covet newer brands such as On and Hoka, pushing its shares down over 12% after hours.

Analysts at Jefferies added that recent investor meetings for Adidas confirmed the company's upbeat narrative, with a strong demand for its 'terrace' sneakers and sport events in summer likely to boost sales growth already in the second quarter.

Shares in JD Sports were down 3.4% by 0744 GMT, slumping to the bottom pan-European STOXX 600 index, while Adidas could not hold onto its gains, and was last down 0.2%.
