I fitted
Divingniknaks Stainless Spring straps to my fins, which I'm pleased with and have made life easier when diving in my drysuit in particular.
My only slight niggle is that the straps don't have a "handle" i.e. something to grip when pulling them on or off.
(I even got a mild complaint from a boatman this weekend who was trying to pull them off as I hung on to the ladder

).
Any suggestions? Has anyone improvised anything?
Cheers...
