Vionic Cheryl II Slip-on

Ordered a 12W which is my usual size. The backs are too wide and the toes are too tight.The quality of the shoes is nice, both uppers & soles, so I am very disappointed in the poor fit.I have several pairs of Vionics, both shoes & slippers, which I like. However, over the past year this is the 3rd time that I've ordered Vionics and had to return because of the fit. So I won't order Vionics again.
