I read the reviews about size and bought the 7.  I am normally a 7-8 depending on open or closed shoe.  The 7 was a perfect fit but for the length.  It was a little short so I returned it and got the 8.  The length on the 8 is perfect but now it is a little wide.  It's slips a little even with socks, but I kept it due to the overall comfort and overall protection when in the yard.
