Trust me on this one. I can't stress enough how important good boots are for whatever types of riding you do. For most women who take up motocross we start with the cheapest pair of little boys boots we can find not knowing much about the sport and not caring to invest big bucks this early in the game. Blisters, bloody ankles, scars, pinching and broken buckles are what follow so be ready to move up if you ride more than three times a year. Your feet, legs and sanity will thank you.
Protection is the name of the game but along with that is comfort.
Like almost every piece of riding gear, women make-do with using men's styles, sizes and fit. It is difficult to find the right equipment that is comfortable and functional at the same time for a women's body. I am pretty much the average woman when it comes to boots. I've hosed them off twice and outside of the scratches they are still like new. The most important feature is the gel padded ankle.
