Jambu Size & Fit Guide
Women’s US sizes · True to US sizing · Wide in select styles
Find your Jambu size with Jambu’s official women’s size conversion — or stop in for a Brannock fitting at our Kettering, Ohio store.
How it fits
Jambu says its sizes run true to US sizing, and it tries to keep sizing consistent across styles. Order the size that normally fits you best.
Jambu and JBU by Jambu styles are made with cushioned memory foam or contoured EVA insoles; many are removable, so you can adjust the fit.
Between sizes
Between sizes? Size up if you wear thick socks or orthotics, or you're on your feet all day. Choose the smaller size if you like a snug fit.
Widths
Jambu offers Wide in select styles. Our size picker shows M (Medium) or W (Wide) for each style.

How to measure
- Stand on a sheet of paper, with your weight on that foot.
- Mark the back of your heel and the tip of your longest toe.
- Measure between the marks in inches or centimeters.
- Measure both feet and use the longer one.
- Measure later in the day, when feet are at their largest, wearing the socks you’ll wear with the shoes.
