The fit of the boot rings on the boots is more complicated that I originally thought. The installation requires consideration of the following:
The dimenensions of your lower leg
The dimensions of the boot
The dimensions of the boot ring.
The dimension of the lower leg of the dry suit.
You have to install the ring low enough on the boot that it will not squeeze your calve. If the boot taper to the foot is too small in comparison to the boot ring, you have to add a v shaped wedge of material to the boot complicating the installation. You obviously cannot alter the boot ring.
The top two inches of a Sperry Figawi boot was cut off and another inch of the liner was removed. In this installation, the ring was installed inside of the top of the boot. I used a double wrap of dry film adhesive tape around the outer surface of the boot ring and McNett's seal cement on the inside of the boot. With a bit of stretching, the new boot top fits inside the ring. Care must be given not to dislodge the dry adhesive from around the boot ring when stretching the boot over the ring. Heat with a heat gun completed the installation. So far, it appears very secure. I will be making it more water tight with Aquaseal or 3M 5200. I have not yet done any leak tests.
I will post my experience of installing the suit side rings as I reach that stage.
