On my second pair, First pair lasted 2 seasons (130+days). I am an ALL Mtn. Rider, not much of a jibber def a jumper and by no means a park rat. I Love this boot, it's the most comfortable boot I have ever had! Fits a half size bigger than shoe size, I wear an 8.5 shoe and have bought both pair of boots in a size 9. I Love the ankle straps on the ZF1's vs. the other Nike boots, I like it tight! I also like the quick release and tightening of the inner and outer laces. Only boot I have bought back to back in 14yrs of riding!
