This instructional video talks about the EZ Spring heel straps. These spring straps make getting in and out of your scuba diving fins much easier, quicker and more convenient. The strap that goes around your heel is a spring. You can just pull it up and over your heel unlike the traditional straps you have to pull to tighten. The spring heel straps will usually snap right in to the place where your old rubber straps fit. The tension on the spring holds it to your foot without any worry of it falling off during your dive.
