The only good thing about these shoes is how fast they arrived from Amazon.  I read about these in Shape magazine.  It was rated at one of the best for high-impact activities.  They really are not for HIGH impact activities!  There is hardly any cushioning in the ball of the foot.  I have average to wide feet and as stated in other reviews, these shoes do run wide.  Too wide actually.  Very surprising in that matter.  I tried to tighten the toe area of the shoes, but when trying to pull the laces tight, the whole toe box area "scrunches" up. Also as stated on other reviews, the laces are too short.  I thought people were being too picky but it's true . You can't take the laces out of the top eyelet to make them longer due to it being part of the shoe so it's like a loose flap.  My feet were sore at the 1/4 mark of a body attack class.  I will wear these for low impact activities, but what a waste because I really wanted a "killer" shoe.
UPDATE:  I really can't wear these shoes at all.  They are so uncomfortable that they are sitting in my closet.  Total waste of money!
