adidas Deportivo Ii Fxg Men's Turf Football Shoes Jr4999 White

Hello, for someone who wears size 40, size 41.5 will create approximately 1.5 cm of space. Such a difference in cleats can affect your performance, but you can support it with thick socks.

Hello, unfortunately we are not in a position to measure and send crampon sizes in cm. However, according to the standard size chart of Adidas, the difference between two sizes is about 0.6-0.7cm. There will be a similar difference between numbers 42 and 42.5. You can see the detailed measurements of each number in the size chart on the product page; you can get more precise information from there. If you have any other question, we will be happy to help.

Hello, aleykumselam. Shoe size is determined by foot length, not age. You can base on your normal sports shoe size, or measure your foot in cm and refer to the size chart to make the most accurate judgment.

Hello, since the fit of the cleats is narrower than daily shoes, it would be more appropriate for you to choose size 43 for comfortable use and performance.
