Nike Kids Collections: Features & Sizing Insights
Nike Kids includes scaled-down versions of iconic Nike shoes and specialized sports models. Each series has unique sizing and performance features.
Key Sizing Insight
Nike Kids shoes generally run true to size, but different collections have unique fit characteristics. Performance models are snug by design, while lifestyle shoes offer more forgiving fits. Always measure your child's foot in centimeters for the most accurate size conversion.
