Size listed here is a US MENS size. Please note that Blundstones are sold and labelled with AU/UK sizes, so the size listed here will differ from the size that may be indicated on the actual shoe. If you currently have Blundstones, do NOT order the same size that is listed on the pair you own (this is the AU/UK size). Refer HERE for more information.
FYI: Blundstone 1/2 sizes refer to width only, not the length. A M9.5, for example, will have the same length as a size 9 with a slightly wider footbed. Essentially a 9.5 fits like a 9 WIDE.
