Hi Alex, FYI. Asics gel sensei 2 is an awesome shoe with perfect cushioning, top model at release time. For this shoes, you can't request for a good grip and fast movement. look at the high and cushion of this shoes i think you will understand. But for a knee treatment, if you got knee problem, this shoes is perfect. For fast movement, good grip, you may look for GEL Blast 3 or 4. you are welcome.
