Slit in climbing shoe

Hi,

While climbing on sharp limestone I managed to cut a small, knife edged slit into the toe of my climbing shoe. I was just wondering if there is anything I can do to prevent it from quickly getting worse. I've uploaded a photo of the shoe for clarity.
Any advice would be greatly appreciated, thanks a lot.

Could try to glue it back together with the same stuff they use to resole them but likely anything you do will come back apart in time there due to the flexing.
