NikeHerren Laufschuh Free Run 2018, Men's Competition Running Shoes, red, 7.5 UK (42 EU)

Hi! I am between shoe sizes. Either an 8.5-9. How do these fit?

Do these fit true to size?

How do these fit? I’m sometimes a 8.5 or 9. Should I do a 9?

On the sizing options for these shoes it says that they're men sizes even though it says they're women shoes, what sizing option should I trust?
