The cohesion 6 is a neutral gait, fairly sturdy shoe. Interestingly enough, the blue and silver ran a bit wider than the gray with pink.  When I mentioned this, my non-believing husband needed to measure and sure enough, there was more than 1/8 inch difference in the mesh across the toe, and other minor but meaningful differences. So if you order one size and it seems tight or wide, try another color in the same size.  For me the small differences meant choosing the color that fit.
