Wow I am surprised at how off the sizing is. I am a narrow 5 1/2 and I ordered a 6 just to be on the safe side. I will probably return and exchange for a 6 1/2. I have never worn that size in my life. Once I put them on my big toe hurt. It put pressure down on it like and the pointy end was also too small. I compared them to some old deflex brand shoes I had and these are way shorter/smaller bottom to botton. I had bought a 6 in that brand. Hopefully the manufacturer takes a second look at the sizing because it seems everyone has an issue. If I put them on without the foot socks they barely even fit. Not cool. Such a nice shoe but what a hassle!
