i was just curious how the full neoprene sleeve shin guards compare to the neoprene velcro shin guards? these don't shift but are hard to get off after training sessions. however they do losen up after they have been broken in and become easier to take off over time never even looked at this style before so i'm kinda curious what others think of the velcro neoprene style mma shin guards. do they shift? does the velcro peel off easily while grappling?
