I purchased the Ingrid Combi Ice Tip along with an ergonomic cane. Both were delivered during an accumulation of 2 feet of snow and ice. I was very pleased that the tip fit immediately on my cane, and extending/retracting the ice tip was very easy. With the ice tip extended, I felt secure walking over icy surfaces, because the cane would hold on to the surface of the ice solidly. I would highly recommend this tip for use on ice or snow, and I think it will be very good on the trail this Spring.
