Steady is an anti-slip protector with seven effective replaceable studs: five under the ball of the foot and two under the heel. It gives an extra firm grip on snow, ice and slush. Must be removed while indoors.
I haven't had the need so far this winter to use these grips, but I am sure they will work well. Had a hard time trying them on my boots - bought large size 9-11 - my boots are size 9. If someone has a size 10 or 11 boot, the large will not fit.
