Dr Marten Jadon Boots US size 7 UK 5

I had these boots for 2 years brand new with gentle wear. Until the platform split for some reason. The crack is 4 inches long. Not sure how deep. I tried to repair with shoe glue but it didn’t work. I removed most the glue. I’m sure a shoe repair shop can fix them. The boots are worn in well with slight creasing, shown in pictures. The soles are in good condition.
