The Leki Trekking Silent Spike Pad is another great innovation from Leki. This vulcanized rubber tip has 6 carbide spikes that provide unparalleled grip while greatly reducing contact noise.

They provide optimal grip in any weather or on any surface such as ice, asphalt, gravel or compact wilderness trails.Import..
