₹ 699 Décathlon
Used them for the first time last night and almost immediately got cramp. I have used other fins and had no problem but these seemed to force me into an unnatural stroke hence the cramp. As the title of the review says some people may find them useful and they are well made but they just don't work for me.
I used these for swimming and snorkelling (without a snorkel) in Greece. Its true there is not a lot of propulsion but there is enough and the fit is excellent if you have wider feet like me. Very comfortable and easy to use and a very good price. Very happy with purchase.
