For many years, shinfinTM fins have helped to give Alona a better butterfly stroke and stronger muscles in her buttocks, stomach and legs, for improved swim technique in the pool and sea. This is because they encourage her to kick from her hips to give her a better swim style. Alona is also a Pilates instructor and there was some discussion about wearing shinfinTM fins on the arms for exercises to strengthen the upper body.
Alona’s review from Jerusalem, Israel
“Thank you for your great innovation! I am very happy with my shinfinTM fins, and I also get a lot of attention when I swim with them in the pool. I love how I can swim the butterfly better now! And I also love how they help me strengthen my buttocks and stomach too, as well as my legs!”
5 years later: “I use the fins mostly in the swimming pool and it is great! At my last vacation in Greece, I took them with me to swim at the sea. Using the fins helped me to improve my butterfly style and strengthen my middle section. I just love them! Thank you Marc for inventing them! Thanks for being so dedicated to your customers!!!”
