Well, let's face it. Plotting things on the feet, it looks pretty stupid. However: they fully serve their purpose. I've dressed for bodyboarding, because I often have bruises on your feet with the hard bodyboard fins, which is very painful. These fins shoes you can on the one hand comfortably on the beach - go without so constantly stumbling - even over larger stones. The shoes fit very well on my feet, I have size 38. Also, the heel strap does the job. I have not even lost a shoe in the water, despite waves. With the fins shoes of course you do not get while swimming or accelerating the boarding as much speed as other conventional blade. But for a relaxing day in the water and on the beach they range all. I have used it almost every day for two weeks, without leaving traces. After removal from the sea or other waters simply with fresh water - finished.
