These are way too small and uncomfortable for a grown adult like myself. I wish they would have said in the title that these were kid's sized, but I suppose I blame myself for not thoroughly reading the customer reviews before purchasing. The Velcro straps are uncomfortably tight, and they tend to rip off whenever I bend my knees dramatically. The same discomfort was experienced with the elbow pads...except that they are even tighter than the knee pads; so much that I could only tolerate wearing them for 5 minutes before taking them off...I'll probably never use the elbow pads again. The knee pads at least do an "okay" job at protecting my knees (so long as they stay on) but I can tell these were meant for children and maybe young adolescents. I'll never be buying these again, nor do I recommend anyone buy them unless they have children....(in which case they might fit perfectly and comfortably on them.)
