I am so far so fulled over 250 km, while only uses roads. Meanwhile, the profiles are mostly over, but I can certainly run more 250 km with it. The pads are soft and not very tight. Only on wet red Pentern they slip ever gone. But to do so expensive pads of Leki and Co. I have already bought later more pads. I really recommend this product.
June 23, 2012: In the meantime, almost 700 km are expired. The pads have not been changed. 20 to 30 km, it certainly make matters with !!!
