Do you know what have I been up to all the recent time? I was diving and diving more underwater - this is marvellous. Once I heard world football cup in Germany started and an idea hit my mind. I've contrived new sports - slippers football. his is a bit hard and weird as one can say but still when you are on a beach this could be of great fun to kick ball to and there on the sand. In addition this crazy sports makes your legs calves stronger and sturdier.
To succeed in flipper football you need small-membrane flippers otherwise playing will be rather hard.
In addition, another advantage of my idea is that if you're the same mad type about diving you'll hardly need to put off you flippers out of water. Just dive and play football, dive again and play. Good luck.
