Leaderfins Monofin Sport for finswimming, Dynamic apnea and CWT Freediving

This is the second pair of monofins I am trying. The first ones from a different supplier were more commercial and frankly felt cheap and indeed disintegrated within a year.These Leaderfins monofins are a totally different level. They exude quality of construction and are a serious professional product. I have chosen the soft version with the exact sizing suggested by the manufacturer. They are really fast and offer a nice workout.In the first use, they felt very tight (my feet were at the top range of the sizing chart) but stayed on without an issue and allowed for a powerful stroke. I may update the review as I use them more on how the fit evolves.As I develop my technique, I may order a stiffer version perhaps one size up.
