If you have been following some of my exploits in five fingers , you have read my disappointment with the KSO for trail running . I continue to run in them on streets and grass without any issues. Well, five fingers has created the right amount of protection to still have a minimalist feel to running on rough terrain. The five finger sport/trek provides enough protection for open field, packed trails, and rocky paths. I broke mine in at my parent's farm in East Texas in their open fields and wooded paths. I found them light and flexible like the KSOs, but with enough protection not to slow down on rocky paths and hard-packed trails. I had no deep bruises in my insole or heel like I did with the lighter KSOs. The only draw back was the occasional long-stem weed between my toes, but that's part of the five finger experience. I like the added traction on both the sole and toe of the shoes . The added plastic covering on the top of the toe seems like it will come in handy on wet...
