About Nike

Nike is an American sportswear corporation founded in 1964 by Bill Bowerman and Phil Knight. The worlds largest supplier of athletic shoes, Nike produces footwear for virtually every sport and lifestyle category. The brand is known for Air cushioning technology, Flyknit construction, and collaborations with athletes worldwide.

How Does Nike Fit?

Nike sizing varies across categories and models. Running shoes (Pegasus, Vomero) generally fit true to size. Basketball shoes (Jordan, LeBron) have a snug, performance-oriented fit. Lifestyle models (Air Force 1, Dunk) can run slightly large. The Air Max line fits true to size for most people.

Sizing Advice

For Nike running shoes, order your normal size. Air Force 1s often run half a size large, so consider sizing down. Dunks fit true to size. For wide feet, Nike offers wide (W) and extra-wide (XW) options in many running models. When comparing to Adidas, Nike tends to run very similarly in length.

Width & Fit Characteristics

Nike width varies by model. The Pegasus and Vomero offer standard to wide width options. Air Force 1s have a roomy toe box. Dunks and Blazers are standard width. Running models like the Vaporfly are narrow for racing. The React Infinity is one of the wider running options.

Popular Models

The Air Force 1 (lifestyle icon), Air Max 1/90/97 (visible Air heritage), Dunk (basketball-to-streetwear classic), Pegasus (running workhorse), Vaporfly/Alphafly (racing), and Blazer (vintage basketball) are Nikes signature models.
