I've been on this planet long enough to know that if something sounds too good to be true, it's probably is. And that there always trade-offs and compromises. When it comes to shoes, it was my impression you had to choose between cushioning/etc or performance. Either your shoes were heavy and offered your knees and joints some relief from hard court pounding, or they were light and let you speed around the court. So how could the SHT-304's be both very light AND as well-cushioned and comfy as claimed? What's the catch with these shoes? They sound too good to be true.
