I usually love NB shoes for their wide toe box.  These shoes are the exception.  They are big, heavy and clunky.  There is a translucent plastic piece that runs around the toe of the shoe and ends with a large piece of hard plastic near the ball of the foot.  This plastic piece does not allow the shoe to flex in the proper place across the top of the shoe.  I'm not sure what the purpose of this plastic is but it makes the shoes incredibly stiff and uncomfortable.  I have even tried bending the plastic with vice grips to try and soften it and even scored it with a knife but it remains unbending.  I cannot wear these shoes to play tennis and will most likely donate them to charity.
