I suggest asking or not buying shoes. These shoes are not accurate. I am 174, but I only wear shoes of size 40. But my classmate 169 wears shoes of size 42. I also have a friend, 183, who is fat and wears shoes of size 42. Brother 172, wearing 4 1 shoes. . . . . . . . There is no strict proportion between the size and height of feet. So, you only know his height and weight, and it's hard to tell what size shoes he wears.
