#10 self-tapping screws in the bottom of my Icemans. Just a dab of silicone adhesive on the threads. Have not had a slip and fall or any leaks in over 20yrs. Couple of bucks for a package of them.

Aren't you afraid the screws will go in too far and make the boots leaky? I have Baffin Titans but have been reluctant to do that.
