Does Nike Run Small?
Forre is still collecting enough reviews to give a confident Nike sizing verdict.
Community fit data is growing. Based on brand sizing information and product specifications.
Fit notes
Runs true to size across most ranges. Pro = high compression, One = medium, Dri-FIT = light. Wide availability of sizes and one of the most body-inclusive brands in activewear. Running-specific products (Tempo, Eclipse) are designed for actual running mechanics.
Watch out for
Quality varies significantly between ranges — Pro products are worth it, some Dri-FIT basics feel cheap. Tight waistband on Pro styles can be uncomfortable for apple shapes.
