I received my ice claws traction cleats over a month ago.  here in center pa. we had a very mild winter this year.  I use them one time to go to the mail box.  they were quick to put on and take off and they grip good.  they are compact and small and easy to put in a coat pocket went you go indoors.  I don't think that they would stay on the shoes for any long walks or runs, but for quick in and out trips on the ice I think they are great.
