I just got myself a brand new pair of Vibram KSO's. The first day I ran with them (14th), I did some sprints and trail running. I ended up bleeing on back of my foot, above the heel. That thin line behind the ankle. So I put some athletic tape and went out for a 9k run(15th) and the tape didnt do squat and made it bleed there AND on the joint below the big toe. For example, Right foot, go to joint that connects it to the foot and on the left side. Skinned was peeled off there aswell. On the Left foot too. Yeah 2 days and filled with blood. Washed them by hand and sticking to my pain free invisible shoes for now... Has this happened to anybody?
