After walking in our big,icey parking lot and terrified that i was going to fall and break something, i went on line to amazon,  keyed in cleats and these great stablicers came up. For $21 i got a pr for myself. You wouldnt believe it but i can run across now with no fear of slipping!!!  Theyre  very flexible and easy to strectch over your shoe. I wear a 61/p2 and fit fine.
