Bodyline shoes sizing

Hello egl!

I would like to order these shoes form Bodyline

<SHOES271>

I know there were problems about the sizing of Bodyline shoes before, and I'm not quite sure which size would be good for me.

I have measured the inner size of one of my shoes,and it's 27.5 cm long. Should I order the 275 one, or do they run small/big?

Thank you for any help!
