Does anybody know a site where it is possible to find these strange monofins with huge footpockets. Most of the time, these fins are made to measure and the main characteristic is the heavy profiled footpocket maintaining the feet and the blade (classical water-way fiberglass) at a very special angle (sorry but I cannot find any photos but maybe some people will understand of what I am speaking about). These fins are now beating all the speed records due to the power generated by the above angle. H. Nitsch and S. A. Severinson have one.
