Is it normal to go up TWO sizes for a running shoe?

Question

I was trying on running shoes today and the girl (who def. knew about shoes) had me in size 11, when normally in fashion sneakers/dress shoe im about a mens 9. Is this normal to go up two sizes? She said i shoudl have a fair amount of room between my toes and the front of the shoe, hence the sizing up. and it did feel alright. Maybe a little big at the back but when I laced them differently they were fine.

im going to special order the shoes since they didnt have the color I wanted but is this kind of normal to go from a mens 9 to 11 for a running shoe???

Answer 1

You would have blisters, if you did that.   Maybe only 1/2 size.

Answer 2

yea i had in the past year

Answer 3

i would go up at least one because your feet get bigger when you run
