fit perfectly - but lack of grip

This is already my third Asics Gel Volley shoes, but in this model, I was not as thrilled as usual I have shoe size 47 and have just ordered the same size again because the last shoes -. Has fitted perfectly.

The cushioning of the shoe is very good - you immediately notice how joints and bones when compared to the older models are protected. But what totally bothers me is the lack of grip! I'm missing a few centimeters immediately jump height and I move slowly and uncertainly in the hall - because I constantly slide! I need your shoes before each workout / game wet scrub and me put a wet towel in the hall, so I do not always wegrutsche. I hope that this will get better in the next model.
