I just got a new pair of Wilson Kaos 2.0 and from what I'm finding out the new Rush Pro 2.5, 3.0 has the same bottom. My problem is they don't slide enough for me, have to be playing super hard to get them to squeak. Will they break in and loosen up or will I snap off at the ankles. Can you recommend a sneak with less traction for hard court, I like to slide. Thanks
