FINIS Positive Drive Swim Fins for All Four Strokes - Ergonomic Fit - Adjustable Heel Strap - Yellow/Black

I cannot say how much I love these fins! They are hard to get on at first, do put them on in the water, but they are worth it. After breaking my ankle and arthritis setting in I had to take up swimming seriously as the only exercise I can do aerobically. (I watch YouTube tutorials for proper technique for more efficient swimming. ) I could never get the proper propulsion to exercise my legs. These fins not only help the foot to propel properly they give added weight, as I guess any fin would, to help exercise the legs. The compact size, comparatively speaking, and in the zipper bag, makes them easier to carry to the pool too. (I did not use these until about 18 months after the ankle break; I would not advise for that therapy.) I ordered by my shoe size, being a US women’s 9 1/2B I ordered the size down as instructed. They are tight but not too long; if I’d gotten bigger they might have been too long to be effective but will not fit a wide or puffy foot. As it is, they function perfectly. After the first use they are much easier to put on and the stretchy straps help there (I tap the ‘toe’ against the pool wall to push them on) though still struggle to remove—they have an odd suction effect like a snorkeling mask, kind of funny actually. But I love them, use them for about 40 minutes of my hour swim (for breast, back, and side strokes after a 20 minute crawl without them.) I keep them on for added resistance during the post swim stretch too doing ankle, leg, and hip circles. Highly recommend for new swimmers.

These are the best swim fins I've ever used. They provide just enough propulsion, do not put pressure on delicate knees, and they force your body into an anatomically correct swim position. Great for training aids and I have been known at times to use them in longer open water swims to help keep pressure off sore shoulders. I wear a women's 11.5W shoe and the XXL is perfect with plenty of room in the elastic back to stretch out. My only complaint is the back is very hard to adjust and if one of the rubber ties becomes undone, it can be a little annoying until you can fix it. But I love these so much I have two pairs -- one to keep with me at home and one at my parents house so I don't have to take them on a plane.

Love that the design of fins as they did not irritate my feet bones and cause inflammation like other fins did. Only problem was the the left foot, the back strap always loosened and I had to tighten continually.

These work well and are easy to get along with. An aid to swim training, and a boost when swiming in the ocean. I also bought longer fins, but they were hard work over distance and less easy to use.

They work well for breaststroke. I wish they were silicone and had a different kind of strap. This rubber rubs the top of my foot and toes slightly and not in a good way. They also need to be adjusted a lot because the knots will come loose. I can easily kick them off if I'm not thinking about it. Not the most comfortable for me, but they work. I swim with the Master's swim team.

great fins for laps, surprisingly strong water displacement despite small size, comfortable and seem well made. Great price value. only negative was had to leave outside for two days to let them off-gas before using but after a swim they are smell-free.

Review of the FINIS Positive Drive Fins (PDF) - Four Stroke Training Fins. I am a recreational swimmer. I’ve owned and used long and short fins, but the FINIS PDF is the shortest yet. It’s also the oddest looking one. It looks like I’m wearing a Frisbee on my feet. I’ve never seen anyone else using the FINIS PDF so it does attract stares from other swimmers. The primary reason that I purchased the FINIS PDF is that I finally decided to master the breaststroke. My breaststroke kick is horrendous and I get no forward motion from it. The FINIS PDF is supposed to be one of the only swim fins that you can use in the breaststroke. After using it for a month, my breaststroke kick with the FINIS PDF has improved, but it is still a work in progress. For this reason, I am happy with the purchase. I wear a shoes size US 8.5 which is a MEDIUM in almost every brand of swim fins. I decided to double check and ask Amazon’s “Ask Rufus” which size I should order, and the answer surprised me - XL. I thought that was a mistake so I searched FINIS’s website and found a size chart for the PDF. For my shoe’s size, US male 8.5 - 10, the FINIS PDF size is an XL. Some reviewers have complained that the FINIS PDF have caused foot pain and skin abrasions. From my experience, all swim fins can cause some foot cramps and pain, but that usually goes away. Skin abrasions are possible if the fins are not properly sized. So far, the FINIS PDF are the most comfortable swim fins that I have ever used. The FINIS PDF are light enough that they will float back to the surface of the water if you drop the fins or they fall off your feet. The are also light and small enough that I intend to pack them in my luggage on my next overseas beach / outdoor swim pool trip. Overall, I am very pleased with the FINIS PDF. They have become my primary swim fins.

UPDATE-Amazing feedback for optimal "slicing" position of feet. LOVE them as that side to side "flutter" went away after 3 weeks of use so that likely means that my "stabilizing muscles" that hadn't been activated got activated and adapted/grew. I now would like to assert that these aren't "specialty" fins but are the only fins one needs for competitive swim training. WOW! works VASTLY better than hoped for breast stroke and side stroke (I am an old school Lifeguard; and will always keep up my side stroke performance) kicks!!! TRULY optimized for these kicks. On scissors kick, I did notice a side to side "flutter" or "shudder", not performance robbing; and I actually believe that ones tiny leg "stabilizing" muscles will get developed to counter act this motion. So, SUPER for breast stroke kick; and good, but not optimized for, scissors kick. I wear a 13 shoe and the XLs are a perfect fit!

Ho appena iniziato ad usare queste pinne positive in piscina. All’inizio ho fatto fatica con la gambata ma, con l’uso, mi sono reso conto che stavo migliorando la posizione. Aiutano molto in questo senso. Sono soddisfatto dell’acquisto e credo che diventeranno le mie pinne di riferimento.

Excelente producto, se nada muy bien en los 4 estilos. Me ha ayudado mucho para mejorar mi patada en estilo pecho. Puntos de mejora, la forma para ajustar la medida porque con el agua se desajusta fácilmente o la tienes que apretar mucho. Y se resbalan mucho al hacer vueltas de campana. Mi talla es 7 Americano y la talla correcta para mi fue Large.

I’ve been using these x 5 days a week and they are fantastic. They do not give you as much speed as normal fins but they help by making you do the kick properly. Can be used for all strokes, even breaststroke. I love them they make my swim fun and has corrected my imperfections.

主人用に購入しました。普通のフィンだと平泳ぎのキックの練習がやりずらいので、このフィンにしました。とても重宝してるようです。ありがとうございました。❗

Excellent fins
