When I played volleyball, I used to come home with sore feet and barely able to walk on them.  Not to mention the general clunky-ness of my old running shoes.  Now my grip level is HUGE, these are so light, my mobility is way up.  Jumping feels great!  And when I'm done my feet feel excellent, sometimes I forget to change back to my normal shoes.  Fit exactly as expected.  Really worth the purchase.  Update: After 1 year of playing 1-2 times / week, these still feel great and offer excellent grip.  Really happy with this purchase.
