Several years ago I purchased a pair of XXXL Force Fins at a going out of business sale. I had never used such an odd looking pair of fins before, but the foot pocket seemed large enough to go over work boots. Your fins work great. An added plus is that even at the bottom of a sizable air gap (in this case about eighteen feet) they are still securely on my feet and I can go right to work. In some circles it is said that real divers don't wear fins. Admittedly, for some hard hat jobs, I don't. But when I do, I wear Force Fin. You have a product worthy of diver gratitude.

Pictured above: We laid 1400 ft. of twin pipe, each section being 20 ft. long, 7 ft. in diameter and weighing 18.5 tons. The diver's main job was to direct the crane operator in positioning the pipe sections, on many days in zero visibility by feel. We also did a good bit of airlifting to insure trench integrity as well as pipe penetration for inspection and repairs. I found your fins especially suitable for moving around inside the pipe.

On an interesting side note, the dive supervisor lost his fins on more than one occasion because of the 18 ft. drop from the deck to the water. After he saw my Force Fins stay on so well, he started using my fins and ordered himself a pair.
