Nike was once the leading sneaker name in China, but its position has weakened sharply. According to the report, the company’s sales in China have fallen about 30%, a major reversal in a market that had previously been one of Nike’s fastest-growing regions.

The decline stands out because China would seem to be a strong place for a sportswear giant to perform well. Even so, the report says Nike has lost relevance with younger consumers, making it harder for the brand to keep the momentum it once enjoyed there.

Another major factor is rising pressure from smaller domestic brands. Chinese competitors have taken market share from Nike, showing how much the local retail landscape has changed and how quickly consumer preferences can shift.

The slide in China underlines a broader challenge for global brands: past success is no guarantee of future growth. For Nike, rebuilding its connection with young shoppers in China appears to be a key issue as competition intensifies.
