Are custom skates worth it?

My kid just turned 15, and is a AAA defencemen, on the ice 5-6 times a week during the season. The main reason we want to get him custom skates are because his left foot is almost an entire size bigger than his right. We used the Bauer fit lab and his left measured at 5.75 while his right measured at 5. Also his feet are very narrow, more narrow than the tapered fit for ccm jet speeds.

We were thinking either ccm or Bauer for the brand. We were just wondering if they are worth it at this age.
