A Size 41 shoe in Europe is analogous to a Size 8 shoe in the UK when converted to UK shoe sizes. This is the same for men's or women's shoes.
A Size 41 shoe in Europe and a Size 8 shoe in the UK would also be a Size 10 shoe in women's and a Size 8 shoe in men's for the American market. On the other hand, or foot in this case, in Japan shoe size is measured directly in centimeters as opposed to a separate shoe sizing method. A Size 41 shoe in Europe would be a Size 26 shoe in Japan.
