Generalmente voy a nadar los fines de semana y por salud y ejercicio decidi comprar estas chapaletas me gustaron desde que las vi y aproveche para tenerlas

I use these swim fins to build strength/endurance for triathlons and long-distance swims and to perfect my kicking form. As an added bonus, it really relieves the anterior ankle impingement by stretching my ankles out. (People often use fins to increase flexibility in their ankles, which improves kick form and power.) Using the fins really helped me build up my quad strength, especially when doing the back stroke. I also find it helps my glute and core strength, but not as much as my quads. I also found I could swim for a longer amount of time without irritating my rotator cuff, which sometimes flares up in a hard swim workout. I wear size 6-6.5/36 in street shoes, and I wear size 7-7.5 in running shoes (second, brooks, and nike). The red X-small were a little too loose on me. They worked fine in the pool, but then I stupidly wore them in the Gulf of Mexico...and lost one of the fins! Boo. By I will buy the same fins in the same size, as I fear the xx-small will be too tight. But I sure won't be wearing them in the ocean, no matter how calm the seas seem!

I bought this for my daughter who is 7 years old and she loves them. She told me that she wanted flippers to help her with her kick and wanted some to looked just like her dad. I had bought myself some TYR flippers but after seeing and feeling here's I'm definitely ordering me a pair also.

Had another pair of fins from another company. The other fins never fit right and I had to buy swim socks to fit and were a pain to put on. To my surprise after 2 years of very little use the back tore. These fins fit perfectly and swimming with them I feel more balanced in the water.

I bought these for my 12 year old son who swims competitively. We've had difficulty finding the right fins. Some caused blisters, pain, or irritation. After trying almost every brand and style of fins we tried these. Perfecto! My son loved these and the fit is great. No need for fin socks or any type of modifications. Thanks Speedo for a great product. My son thanks you.
