Sizing is true based on mass-market brands.  If you generally wear an even size (i.e. 10 US) make your sizing decision based on your foot width.  If you have a more slender, narrow foot, order the next half size down, if you have a wider, high-volume foot, order the next half size up.

The lasts we use to build our footwear are slightly longer than traditional lasts and will allow you to order the next 1/2 size down without issue.

Your pair should fit snug out of the box, leather will adapt and form to your feet over time.
