Katsuji’s review: Cardio exercise fins for stronger kick with no cramps
“I found shinfin
Yes, they do give you good cardio exercise and help to strengthen your kick in the proper way for good swimming – without the cramps that you get from normal foot flippers. We get a lot of good feedback like this. I can help you to take the fins off quickly too. Did you try this quick-release method from the tips?
Take fins off – using inside buckle only (~5 seconds per fin):
1. Wet fins.
2. Undo inside buckle only by:
(a) Pull out strap tail from under strap.
(b) Keep pressing arrow gently to unlock buckle.
(c) Pull other side of strap firmly, so strap slips right out of buckle.*
3. Slide fin off leg (leave outside buckle done up).
“This certainly helps!” (after reading fin quick-release tips)
“Yes, please feel free to use any of my message for your reposting on your web, with any revisions/editing that you may find fit. I think I was lucky enough to have been able to spot the shinfin
