The shoes were really stiff and hard the first time I tried on.  I wore them around the house to break in a lil bit.  I've only ran 2x in them and I'm still trying to get used to thick soles and cushioning  On my last run, I developed a blister on the back of my foot.  I'm hoping to break them in a lil more and God willing they will feel more comfortable.  For now, I'm not impressed with all the Hoka hype.  : /
