Can you recommend a glue for cracked polyurethane shoe sole

One of my expensive shoes has a crack across the sole 2' wide and full-thickness (about 6mm) under the ball of the foot (fortunately not to the edge - just in the middle). So far it looks like I should use a urethane glue to fix the crack. I don't want to just resole leaving the crack, and haven't had joy with shoe goo in the past - I noticed a Selleys Shoe Glue but the picture shows resole-ing - I'm wondering if that also is a urethane glue. So my question - for fixing a full-thickness crack in the sole - and I'm hoping I won't need to also stick on a new sole plate - what glue/bond would you suggest ?
