I broke my foot this spring and so I ordered these shoes because I heard they offer they best protection and I didn't feel like re-injuring myself. These shoes do not mess around. They are heavy duty and I no longer have the fear of jamming my foot and re breaking it. They also offer stiff soles and amazing grip on the pedals so your feet stay put while you're riding. I don't know if Five Ten offers a woman's Impact, but as a female with a narrower foot, these are super comfortable and fit my feet perfectly, there was no break in time. The only con is that because they are such a serious shoe they take a REALLY long time to dry out after a wet ride.
