Good point. The wet towel has saved me on many occasions from possible injury. Yonex also make a shoe spray you can use that you spray onto the bottom of your shoe. It works very well.
 
Let me point out here that a wet towel needs to be damp enough to provide some moisture but not so wet that it leaves puddles on the floor. As we all know, if you have too much moisture on the base of your shoe then the water gets between the shoe and the floor and you do not get any grip at all.
 
A small towel is all you need, preferably dark colour because it will get very dirty. Wet the towel and wring it out to get rid of excess water. Place it on the floor away from the sides lines so that it doesn’t interfere with play. A quick walk over it with each foot is usally all you need but make sure you test the grip with the floor off court to ensure there is not too much water. Never test on court as you could be leaving excess water on the court which is highly dangerous. Only return to the court when you have a decent grip.
 
I don’t like the sweaty hand method because you’ll be transferring the dirt to your hands all the time. It’s not very hygenic. At least with the towel you can place it in a polythene bag after the game. Have a dry towel handy to mop up the moisture patch by the side of the court to ensure nobody slips on it.
