As already described in several reviews, the band buckle is too low, so that one likes to paint loses powerful flippers. For normal, European foot most unsuitable. The buckle attachment point is very small and are probably in decent use soon after or breaks. In addition, these fins NOT FOR booties are suitable. I switched on the Cressi Rondinella: Vollfußflosse which has a very good driving, good sitting and is lossless :-)
