What way are your Nimhs cut?

Thinking of cutting some of the side walls away at the front of some fresh shells, toes feel a bit bunched and middle toes go slightly numb after a while.

Don't want to remove the bridge across the toe box really, previously it felt great but topsides just felt a bit unsupported and floppy. Also I felt my foot slipped forwards more making the skate feel shorter in length.
