Leaderfins Ice with C4 400 Footpockets


Jan 7, 2018
Just "build" a new pair of fins and wanted to share my experience with pairing Leaderfins Ice blades with C4 400 footpockets.

TLDR: glued them and it seems fine. Maybe should have gone for the C4 adapter set and mounting screws though, would make it easily replaceable, but adds ~25€ per fin.

Started with the blades, here compared to my Ultrafins speedy

Then got the footpocket

and fitted on the fin to see if it works

The next step was to put the blade in the pocket and glue it with super glue aka cyanoacrylate. I glued it on the bottom and top and after that the rails by dripping in some from the top.
The issue is that the gaps seem to be quite big, so I'll have to see if it actually holds.
The final result looks quite:
