The Leki rubber tips are ideal for hiking on concrete because they grip the surface well and keep the tips from clicking against the ground. They are easy to take on and off and are compatible with many types of trekking pole tip, not just the Leki Flextip. Ive also used them in areas with fragile vegetation as not to disrupt the ecosystem or regrowth efforts by potentially damaging the flora. Four stars out of five because they can fall off if you happen to be hiking in muddy conditions.

I bought these to go on my Black Diamond Trail Ergo Cork Trek Poles to minimize my impact (and noise) on trails. Theyve worked like a dream.
