For example, Adidas size six men’s shoes in the Adidas shoe size chart is a size 6.5 Nike men’s shoe according to the Nike shoe size chart. This is the reason why you must measure your feet to get perfect measurements for your full shoe size.

Sole materials

Nike shoes are usually made of a rubber outsole with different sole patterns that help to give you more traction on various floor surfaces. This is very useful for athletes when running on different terrains or the basketball court. Adidas uses boost technology that uses compressed and molded pallets to make some of their shoes. This material also plays a big role in providing you with great comfort in Adidas shoes.


The comfort of a shoe is how well the shoes fit you, so if a shoe has a stunning design, that doesn’t mean it will be comfortable to wear. It has to have the perfect fit with no friction or rubbing and able to provide enough arch support for your feet. Most people find Adidas shoes super comfortable to the extent that you can use them for your daily use. This is because of their full-length midsole that provides support for your entire body. Nike isn’t left behind with new technology in its midsoles and inner cushioning that guarantees to provide you with excellent comfort apart from its shoe size.

Shoe design

Nike shoes are popular, especially among the millennials, because of their appealing shoe design and their variety of styles and colors, which gives you many products to choose from.

Weight of the shoes

The boost technology used in Adidas shoes makes them versatile, which means you can use them for sports activities and also for everyday wear. This makes the shoe light and also gives them excellent arch support, cushioning, breathability, and flexibility.

However, most wearers are concerned if the shoes will properly fit them, or will they be a little too big or too small. This concern is because most people aren’t able to select their right shoe size. Some of the shops and retailers you visit may provide you with the shoe sizes in metrics used in other different countries, and these sizes are standardized in the U.K., U.S., and other European countries. They’re given in inches, centimeters, or other measuring units depending on the country of origin.

Many customers with wide feet find it hard to get that can fit them, and Adidas has created shoe allowances, especially for people with broad feet for more comfort, so if you’re a size nine, you can still wear a size 9.5 and still be comfortable. You also get allowances on broader feet and the right size on leaner feet so that your shoes aren’t too big. It’s always advisable to check the Adidas shoe size charts to find your accurate size.
