Hello all... this is my 3rd month running barefoot. I tried running barefoot for fixing my running form after an accident during a sprint exercise. I found out my heart rate is lower when running barefoot, then I became more serious studying about barefoot running. So far I can run 10 km (6+ miles) barefoot albeit slow. Still feeling sore on the soles behind the toes - I guess this will disappear once the technique is refined.
