Whether you’re just learning to swim or are an aquatic aficionado, every swimmer could benefit from a good pair of swim fins. The right pair will help you swim faster, encourage the development of proper technique, and even improve your overall cardiovascular health. Swim fins come in a wide variety of colors, designs, and technique-enhancing builds, so you’ll never have trouble finding a pair that fits your needs. Here are some fantastic swim fins that we highly recommend!

Buying Swim Fins

Here are some factors that you should look into:

  • Materials: To ensure your swim fins will actually enhance your aquatic experience, you need to invest in a pair that are crafted with high-quality materials. Make sure to look for fins that are made with natural rubber, polypropylene, or silicone, as these materials are waterproof, naturally buoyant, and will provide a supportive yet comfortable base for your foot.
  • Blade Length: Before purchasing swim fins, you should know which blade length will best suit your needs. Long blades are best for swimmers looking to create long strokes, increase their swim speed, and get the best underwater workout. If you are a casual swimmer looking to develop the proper technique without becoming fatigued, you should invest in swim fins with a short blade.

Best for Speed: Speedo Switchblade Swim Fins

This design allows you to increase your speed without having to sacrifice proper technique. The fins are made with high-quality 100% rubber that is durable yet lightweight. They feature extended foot pockets for added comfort and mid-foot flex points that help to eliminate cramping, meaning you’ll never get tired of using these fins.

The fins are crafted with durable silicone that is flexible and supports your feet throughout the kick cycle. They come in 13 colors and with technique-focused side rails that encourage you to develop a proper kick that starts at your hips, not your knees.
