The Cohesion 10 fits me very well except for being snug at the toes.  I will go up a half size next time.

I am very impressed by these shoes.  I wear them for walking, not running.  The heel has "cush" that softens the feel of pavement and the sole is wide across the ball of the foot for great side to side stability.  The fabric upper provides good ventilation.  The shoe's supple flexibility makes walking a pleasure.

Overall, they are exceptional for walking and they should work well for running on pavement and treadmills.

I returned a different pair of shoes that cost twice as much because they did not match the comfort, support and flexibility of the Cohesion.
