I'm new to this forum and about 12 weeks into barefoot running/barefoot living. I feel like I'm progressing well, but I find I tend to be a little obsessive about tweeking my technique. Do people notice if they hold tension in their glutes as a way to increase their forward propulsion? When I increase the tension in mine I effortlessly accelerate. It feels like a push more than a pull (as when you accelerate with your quads). Is it practical to hold tension for very long runs or will it insidiously lead to wasted energy and other compromises? For the time being the soles of my feet can't handle too fast of a pace for too long. I'm hoping this will eventually resolve.
