Review: Great for learning to mermaid swim! - The shape of the fin doesn’t match most mermaid tails, but it’s a wonderful beginner fin for learning to mermaid swim. It was recommended to me and I was also told the linden fin shape (think standard mermaid tail) takes a bit more strength to control properly. Because this fin is made with soft edges it’s safe to use in swimming pools with other people nearby (though please still be respectful and try not to hit other people with it). Some other fins are stiffer with sharp edges and could hurt other people if they got hit with it. Think about your swimming environment when choosing the right fin for your needs, as well as your swimming level. This is a great fin for getting started. I wear mine with neoprene socks to avoid the possibility of blisters, plus my sock have grip bottoms so when I’m not wearing the fin and walking on wet tile I don’t have to worry so much about slipping.
Review: Great and comfortable monofin - Love the soft material and foot pockets. People have said that you should size up when ordering this fin because Foil’s foot size chart was a bit off. As I looked at their chart, I saw that I was a small, but since people have recommended to size up, I did. I got a medium instead of a small and I would say a medium fits just right on me. I have no problems swimming in it, so maybe when you want to order this fin, I think it wouldn’t hurt sizing up. It doesn’t give be blisters at all. It is very comfortable to swim in, like I mean really comfortable. I absolutely love it. People also say that they had some tears by their foot pockets, I haven’t had that yet, since mine is a new fin but I’m sure with more use, that will happen. I also think the price is just right for this type of fin. Update 2022: so it has been 3 years since I got the Monofin and let me tell you how great it still performs! No tears, though a few “usage/stretchings are visible but still fits my feet All in all, great fin, and would definitely recommend buying it. Update 2026 : Well my monofin officially has wear and tear. The medium size has became loose and huge on me. I’m allowed a few kicks and then it comes off. Definitely ordering another one though and this time will go for small size so hopefully it lasts much longer on me. still an awesome fin, still recommend! Also, I wouldn’t recommend sharing it, especially people with bigger feet than you, definitely a faster wear and tear.

### ⭐⭐⭐⭐⭐ Great for learning to mermaid swim!

### ⭐⭐⭐⭐ Size chart is unreliable for Women's 9
*by K***K on December 10, 2022*

I tried both sizes Small and Med and I wear a woman's 9M. The sizes are very different and the small was crushing my foot because it was so narrow (about 3 1/4 wide X 9 1/4") and the M was bigger in the foot pocket so my foot wobbled the entire time I swam and I got cramped for trying to control that. I got foot pain just from trying on the Small. I have a slender 9M foot. Totally disappointed in FINIS even though I have many FINIS swim equip. products. This monofin size Small was recommended but that's a total fail and the M is a poor fit too. I also have a BodyGlove Linden which has a very large stiff blade and I found it to be comfortable and it has adjustable ankle straps. However for the blade was a little difficult to control and I don't know if the construction (2 materials) will hold up to work outs. I got some muscle cramps from it. I am a fairly strong swimmer and rarely get cramps. I wanted the the Finis Foil to build strength and I might try the med with booties but overall still disappointing.
