I wear a 6.5 in other shoes but since there are not half sizes, I ordered a 7. I should have ordered a 6 because the 7's are a bit too big.  The shoes are comfortable but the side of the shoe digs into foot a little. I expect this to go away with wear.  I can wear these on my 10 hour shift and don't have knee or back pain. My feet are not fatigued.

Overall I am happy with them.
