Swim fin tethers – what is it, what are they, how are they used correctly in surfing

Swim fin tethers are a valuable accessory for swimmers and snorkelers, providing an extra layer of security to prevent the loss of fins while in the water. These ropes consist of straps and attachment clips that connect the swim fins, ensuring they stay firmly attached to your feet.

Installing swim fin tethers lets you swim confidently, knowing that your fins will remain in place even during vigorous activity. This guide will walk you through the steps to properly install swim fin tethers, allowing you to enjoy your water adventures without worrying about losing your fins.

How to use

Installing swim fin tethers can help prevent the loss of your swim fins while swimming or snorkeling. Here’s a general guide on how to install swim fin tethers:

  1. Gather the necessary materials: You’ll need swim fin tethers, usually sold as a set with straps and attachment clips. Make sure you have the right size for your fins.
  2. Prepare the fins: Remove any dirt or sand from your swim fins and ensure they are clean and dry before installation.
  3. Locate the attachment points: Most swim fins have a small hole or opening near the back of the foot pocket where you can attach the ropes. Look for these attachment points on each fin.
  4. Insert the attachment clips: Tract one of the clips provided with the ropes and thread it through the hole or opening in the fin. The pin should have a loop or hook on one end.
  5. Secure the clip: Once the pin is threaded through the fin, secure it by looping it back through itself. This creates a secure attachment point for the rope.
  6. Repeat for the other fin: Repeat the process for the second fin, ensuring that the attachment clips are securely fastened to both fins.
  7. Adjust the strap length: Most swim fin tethers have an adjustable strap connecting the two fins. Adjust the belt size to be taut but not too tight when the fins are worn on your feet.
  8. Test the fit: Put on the swim fins and check the fit. Make any necessary adjustments to the strap length to ensure the fins are comfortable and secure on your feet.
  9. Trim excess strap length: If the strap is too long after adjusting, you can trim the extra length using scissors. Be careful not to cut the belt too short, as you may need to readjust it in the future.
  10. Final check: Double-check that the ropes are securely attached to both fins and that the strap is adjusted correctly before entering the water.
  1. Use lubrication (optional): If the attachment clips are difficult to thread through the fin holes, you can apply a small amount of lubricant, such as soapy water or silicone spray, to make the process easier. This can help reduce friction and allow the clips to slide through smoothly.
  2. Consider using heat shrink tubing (optional): To provide additional security and prevent the clips from slipping off the fins, you can use heat shrink tubing. Slide a piece of heat shrink tubing over the attachment clip and use a heat source (e.g., heat gun or hairdryer) to shrink it, creating a tight seal around the clip and fin hole.
  3. Test the tethers before use: Once installed, give them a gentle tug to ensure they are securely attached to the fins. This will help prevent any surprises while swimming.
  4. Practice swimming with the ropes: If you’re not accustomed to swimming with tethers, it’s a good idea to practice swimming in a controlled environment, such as a pool, before using them in open water. This will allow you to get used to the feel and movement of the ropes.
  5. Regularly check the tethers: Inspect the tethers and attachment clips before each swim to ensure they are in good condition. Look for any signs of wear, fraying, or damage. Replace any worn-out or damaged parts to maintain the ropes’ effectiveness.
  6. Follow manufacturer’s instructions: Always refer to the specific instructions provided by the manufacturer of the swim fin tethers you’re using. They may have additional tips or guidelines tailored to their product.

Remember, swim fin tethers are designed to prevent the loss of fins, but they do not eliminate the possibility. Swimming in appropriate conditions and taking precautions to avoid losing your fins, such as avoiding strong currents or waves, is still essential.


Installing swim fin tethers is a straightforward process that offers peace of mind while swimming or snorkeling. You can ensure a comfortable and secure fit by securely attaching the ropes to your swim fins and adjusting the strap length. Remember to follow the manufacturer’s instructions and consider using optional techniques like lubrication or heat shrink tubing for added security.

Regularly inspect the ropes for wear or damage and practice swimming with tethers before venturing into open water. With swim fin tethers in place, you can focus on enjoying your aquatic activities while keeping your fins securely attached. So go ahead, install your swim fin tethers, and dive into your water adventures with confidence!
