Bought these for light travel where diving was not the major activity. The break down function is great. It allowed me to stuff them in a smallish duffle pack my other fins would not fit in. Amazingly these fins seem to work as well if not better. I might just use these from now on unless I get a pair of free diving fins.

I know several people who swear by these fins, so I was anxious to buy a pair. I wear booties with thick soles for shore diving in lava and other rocky areas. The food pocket fits side to side but the top and bottom of the pocket taper together too much for my boots, making it uncomfortable on the tops of my toes. For most booties, the taper would be an advantage, eliminating up and down slop in the pocket. I wish they had worked. I didn't want to downgrade the rating based on my special circumstance. People I know say they get a lot of power out of them and they are lighter than some fins.

Very pleased, great fins for scuba diving.
