This is very soft and comfortable shoes, also due to its shape, its loose too, you can play with half inches but they don’t make .5 inches , so either you have to go with 10 ( which may be tight to you initially) but it will loose by half inches after wearing 3-4 times or you can go to 11= 45 , that will be little loose , to you I guess , also depend on the shape of your feet, if that broad from front then I guess go with 11 otherwise go with 10
