MARCOMEN Leather Sneaker Shoes Men's Shoes 15221009Z1

Hello dear customer, thank you for your interest. Our product is in the sneaker category and our shoes are generally in standard size, so you can prefer the size you use daily. However, since you wear half a size (40.5), it is technically not possible for us to give you a clear size recommendation. Since comfort and your usage habits are important, we kindly ask you to consider the width of your foot and the similar sports shoes you have used before. Additionally, you can benefit from the size experiences of other users by reviewing the customer comments and questions section on the product page.
