The shoe feels really good in regards to the zero drop but the shape of the toe box is so severe, that if you have a longer second toe or your toes don't shorten quickly towards the little toe, your toes may hit the end of the shoe if you order the same size as you always have.  I returned the shoes for a larger size, I have not received the new size yet but hope they fit now since I love the zero concept and larger toe box, just not the severe slope of how it cuts back...we will see.
