Find Your Nike Sock Size
Choose your shoe size and get the perfect Nike sock fit. Supports US, UK, EU, and CM.
If you’re using CM, measure your foot from heel to toe using a ruler or paper.Finding the right sock size is just as important as picking the right shoes. Whether you’re hitting the gym, heading to school, or going for a run, Nike socks are designed to support your foot — but only if they fit correctly. This guide breaks down the official Nike sock size chart for men, women, and kids, so you can find the perfect match based on your US shoe size or foot length.
👟 Why Sock Fit Matters
A poorly fitting sock can cause discomfort, blisters, and even reduce performance. Nike socks are designed to mold with your feet and offer arch support, compression, and sweat control — but only when they fit as intended. That’s why knowing your correct Nike sock size is essential before you buy.
