I fell in our driverway and really was hurting for over a week.  First thing I did was order these grippers.  They work great!  I was out for a 3.5 mile walk today on snow/ice covered roads with no problems!  I still am a careful walker after the recent fall but these give great assurrance that all will be well.  I have only used them 3-4 times so really don't know how long they will hold up.  Some of the walking is done on bare roads and it takes a bit of getting used to that feeling with the grippers on.  They are getting me out walking again!
