I use these when I ride on a recumbent trike where my feet are out in front of me. Very good reflective qualities and bright colors make me more visible. Good velcro! I also use them for my dog when I take her along for the morning bike ride - two bands go together to make a loose "collar" for her that will make her more visible and reflective in case she would somehow get away or just to make us more noticeable at intersections.
