text: I have medium width feet, and wear a size 10 shoe.<br />The shoe stretcher does not open wide enough to stretch the top of my sandals.<br />I tried them on a pair of ballerina flats. Still not wide enough.<br />My daughter who wears a 7 1/2 used them and they were fine.<br />I suggest purchasing a size up. It's not like I have super wide feet. They just don't open enough, even with the plastic things.<br />The quality is good, thus the 2 start rating.
