Hi I currently wear a US 7.5 size of SH9100. Looking to get an SH8500 and wanted to check with fellow BCers who have used/use SH8500 if I need to go up a size t US 8 since it is considered to be a wide shoes.
No you don't. The fit of the 9100 is actually slightly narrower so you might actually feel more roomy with the 8500.
