A couple weeks ago I received my first pair of spikes , the maxcats. I found them to be too narrow in the midfoot, but the width was perfect in the toebox. I thought that was a problem (midfoot being too narrow). So I ordered the air zoom superfly P2s and received them today. To my dissapointment, it has a narrow midfoot as well. Is it okay for the midfoot to be too narrow, because in the sprints I have to stay on the balls of my feet anyway? I did a few workouts in the maxcats and didn’t have much problem with the fit. The narrow midfoot only irks me when I put on the spikes.
