EXCELLENT on ICE we had for last few days sleet then snow then sleet then snow so we have around 3/4 inch total it froze real nice since out highest temp is 23.7 now . Never needed them last year put them on walked out on all te ice and snow mostly ICE had no trouble walking with these you could most likly run if had them on tightest enough and would not fall. I am 73 going on 74 so do not think would try it.
