When wearing regular foot fins, it is often very slippy and dangerous climbing up and down ladders and steps. You need to do this at the pool, the sea and when climbing on and off boats. So some people have to put their foot fins on in the water, and take them off in the water too. This is difficult and can be dangerous. Doing this next to a boat in choppy water can be very dangerous. There is also a danger that you may drop your fins and loose them when they sink down into the depths of the water.
