I  spent $150 for these.  I bought them for my registration work in the hospital, which means I haven't gotten to use them for running.  I haven't had these shoes for 6 months & they have already separated from the sole.  The seller has a return policy for far less than that, so I can't even exchange them.  I attached a photo, so you can see the separation is at the most needed part of the sole: the ball of the foot. I will not be using or referring this seller again due to the poor quality of their product.
