I ordered my normal size but they barely fit--- way smaller than I expected, and they hurt my toes.  I sent them back and got a full size larger than I normally wear.  They fit better, but still not well.  Two complaints:

#1: I like a sneaker that i can lace loosely and then slip on and off easily.  These cannot do that, because of how the heel is cut.  The heel curves way in onto your foot so you could never take them off without unlacing them fully and really prying them off.  Annoying for a casual shoe.

#2: the sole of the shoe tapers drastically under the foot, so the part that actually touches the ground is much smaller than the surface area of your foot above it.  The result is that it's much easier to mis-step and twist your ankle. Very very poor lateral stability, almost scary.  I sent these back.
