Monofins are an excellent training aid for practicing butterfly kick. Monofins significantly strengthen the kick and help swimmers to move faster. Monofins can also be used in swimming pools, as they don't endanger other swimmers, but you can also take them in open waters and enjoy swimming in the sea. You can choose from different types, sizes and colors. The professional swimming brands Finis and Mad Wave (which can be relied on) took care of the quality of workmanship. Have a look at our website and choose from our offer of training monofins, non-traditional monofins and for children.
