Finis Foil Monofin - Rubber Swimming Fin for Men and Women Swim Flipper to Strengthen Legs and Core - Adult Swim Fin for Swimming and Pool Accessories

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.

I ordered this monofin for my son to help him with his dolphin kicking technique used in various strokes that he competes in. I was rather hesitant to place the order because there was NO size chart which made this pricey purchase somewhat ambiguous which is what held me up from ordering it months earlier. I literally held my breath. Fortunately, the material was very soft and pliable and he was able to stretch the material to fit his size 11 feet comfortably. The product seems to function as designed. Just wanted to include a size chart so others would be able to reference which sizes were covered within the ranges listed.

We bought this to feed my mermaid fixation I've had, oh, all my life. :) My son (10 years old, size 6 shoe) and I (size 8 shoe) trade off using it in the pool and it provides good power with a dolphin kick. Easy to slip on and off due to the large stretchy heel bands, the only trick to this is remembering that you can't walk in it. However, it's easy to sit on a step of the pool and put it on, then mermaid your way across the bottom of the pool at top speed. It also works to swim sideways and along the surface of the water, so you can get in a good workout. This is made of good quality materials and doesn't show any signs of wear despite frequent use.

great for my 10 years son who wanted to improve his butterfly kicking

I needed a monofin to teach my daughter butterfly for swim team. This was perfect. The sizing was right on. We got a small, and it fits both her and I (sizes 7.5 and 8.5 womens). It's too small on my son (size 9 mens), which we rather expected based on the sizing chart.They're about as comfortable as any fins I've worn through the years. Extended wear will get uncomfortable, but they work well and stay put for swimming some training and teaching laps.

I really like the way this fin swims, but I can't wear it for more than a few minutes before it hurts so badly that I must take it off to avoid blisters. I have tried 2 sizes, medium and large, but perhaps an extra size larger and some neoprene socks would help.The problem I have had is in the toe area, where the toe hole is cut out with a razor blade during production, which leaves a sharp edge where the toes poke through, and rubs badly. My normal fins have a longer toe pocket that the toes do not poke through, and I have no comfort issues with almost any other regular fin I have tried.I really wanted this to work, as the core engagement I get with this monofin is great exercise, and different from my usual swimming. It seems very efficient underwater, speed feels good, and I can go a greater distance on one breath, it seems. It's also easier to control for a beginner than other monofins I have tried, and is not likely to injure anything you're swimming with, or yourself, due to the soft rubber construction.

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.

Reduced qualityEs la segunda aleta que compró y claro que siento la disminución en la calidad de la aleta !!!! Uno sabe que no durará mucho tiempo y encima le suben el precio
