I opted for mountain bike shin & knee guards. A little more expensive but covers more area. No bruises yet. Light weight.
Negatives are the 4 fastener straps. Takes time to put on but light enough not to affect running.
Also recommend Jock cup, Wrist shield, Chest protector, face mask and helmet. Never too much protection.
Release the ball, get in a defensive posture quick by back stepping. Be ready to back up any place you can.
Finally practice, practice,practice. Everyone hates seeing walks, no freebies allowed.
