It seems that the chinese Monofins producer bin fins upgraded there Website.
BinFins Web Site
Now you can watch the site in different launguages and have an easy online order form as well as a pdf version of there product catalog. In speedswimming these fins have quite a reputation, and guillaume Néry also wears them. It seems that they are aware of the freediving junkies always on search for better equipment as they offer different types of Monofins, like a special version for women, and a speciel version for freediving.
By the way, are there any Bin fins user outhere who wants to give a review on there Monofins? I only found some comments on french freediving forums till now
Have a nice day,
Christophe
