THANKYOUVERYMUCH MR. ROBOTO It may have a simple, all-American name but we know that the BONNIE from JC is secretly (well, maybe not so secret) a robot heel from the future. Aerodynamic wedge with laser-precision style oxford detailing. It was designed to make us quickly fall for its charms. And it worked. Recording device not included. 4 1/2" heel and 1" platform. Leather upper and lining, man made sole. Fits true to size. Size US8 insole measures 9 5/8" or 24.5 cm. Each half size is 1/4" or .5cm difference.
