What Nike Shoe Size Should I Choose? Complete Size Guide

What Nike shoe size should I choose?

Finding the right sneaker size can be difficult, especially when shopping for Nike second hand online.

Nike uses several sizing systems, including EU, US and UK sizing. Different models can also feel different depending on their construction and fit.

The safest approach is to measure your foot and compare it with Nike's official size chart. Nike also notes that the CM size shown on a shoe label or box is not the same thing as your actual foot length in centimetres.

A short history of Nike

Nike began as Blue Ribbon Sports in 1964, founded by Phil Knight and Bill Bowerman. The company initially focused on importing and selling Japanese running shoes.

In 1971, the company moved toward its own Nike brand and the Swoosh became a defining part of its identity.

Nike has since developed shoes for running, basketball, football, lifestyle and streetwear.

That means there is no single fit that describes every Nike model.

How to find the right Nike size

Step 1: Measure your foot

Measure both feet and use the larger measurement as your starting point.

Step 2: Check Nike's size chart

Compare your measurement with Nike's current size guide.

Nike provides separate footwear size charts for different categories, including men's and women's footwear.

Step 3: Consider the model

Your usual Nike size is useful, but the model matters too.

A flexible lifestyle sneaker can feel very different from a structured performance shoe.
