Flat sole that measures 1/2" at the toe and 3/4" at the heel.

It is recommended if you wear a half size at all, go up. (ex. 8 1/2 go up to a 9)

The measurements are from the top of the toe to the heel. 

YOU WILL WANT A LITTLE ROOM AT THE TOE END AND THE HEEL END--PLEASE COMPENSATE FOR THIS. 

MEASUREMENTS ARE NOT FOR THE FOOT SIZE, THIS IS THE ACTUAL MEASUREMENT OF THE SOLE. IF YOU PREFER ROOM ON EACH END OF THE FLIP FLOP...GRAB A RULER AND MARK THE MEASUREMENT. THESE MEASUREMENTS ARE FROM THE BIG TOE TO THE HEEL.
