When downhill biking I find that my feet keep slipping off the pedal making me bang my shins on the pins or run off the trail altogether. I was reading great things about Five ten impacts but I want to try out clipless pedals too. Point is I don't have enough money for impacts and SPD shoes so I wanted a pair that I could use for both flats and clipless. The Five ten hellcats seem nice as they have the same rubber as the impacts and I can clip them in as well. I just don't want to buy clipless shoes and clipless pedals only to find out I don't like the system. Any input is much appreciated.
