Leave your shoes on. Leave your shoes on. Leave your shoes on as you don and doff your ION K-Lite Zip Knee Pads. Protection, comfort, all that good stuff is there too, sure, but: you can leave your shoes on as you take off and put on these knee pads. They have a zipper, so you can leave your shoes on. For anyone who's teetered on one foot in a muddy parking lot while messing with knee pads, this is significant!
