Hiking Boots & Shoes Size Chart
Measure your foot at the end of the day, standing, with hiking socks on.
How to Measure
Foot Length: Stand on a piece of paper, mark the back of the heel and the tip of your longest toe, then measure the distance between the two marks.
Hiking Tip: Leave about a thumb's width of space in front of the toes. If you are between sizes, size up for toe room on long descents.

Notes: Oboz uses US sizing. Most boots run true to size; if you wear thick hiking socks or are between sizes, size up for a more comfortable fit on long trails. Width options may vary by style — look for Wide (EE) listings on the product page if you have a wider foot.
