Some information about half sizes.

The half boot sizes produced by Mongrel are always the same size in length as the preceding full size. As an example a size 7 1/2 boot is the same size in length as the size 7 boot. The difference is in the girth (the width across the forefoot), which, in half sizes, is manufactured several mm wider than the preceding full size. So the half sizes feel bigger and are recommended for those with wider feet.
