Use these foam insoles to snug up the fit of your boots or shoes and provide extra padding. Each full-sized pad is whole sized.  Select your US size, sizing up if you are a half size. These pads can sit on top of the footbed, or if it is removable, the pads can be placed under the footbed. Size 11, order a size 10.  Those who prefer a narrow shoe should consider these as an add-on to medium sized options to improve the fit.
