Well....That depends on whether you are running with or without the spikes in. This is a true cross country shoe and is therefore designed to be utilized on dirt, grass, mud etc. If you are running over a course that includes pavement during sections I would suggest utilizing plugs instead of actual spikes and you will have no ill efefcts. Of course. if you are planning on utilizing the Shift as a road shoe I would say that's a bad idea.
