This is a sizing guide, not a fit guarantee
If you are new to Boombah footwear we have provided a sizing guide below to help with your selection. The biggest determining factor of size is foot length. Please note that all of our men’s shoes are a standard D width and the women’s are a B width. If you fall outside of those widths you should adjust your choice accordingly. If you have ordered from us in the past and have found the size you prefer, we suggest you continue to order that size.

For information regarding the fit of specific models please refer to the sizing tab of each product page.

    Measuring Your Foot
  • While seated, place your foot on a piece of paper in front of you. Be sure to wear socks.
  • With a pencil, trace around your foot. Hold the pencil as straight up-and-down as possible and be sure that your pencil remains in constant contact with your foot during this process.
  • To find your foot length, measure the length of your foot at the longest point
  • Be sure to measure both feet, many people have slight differences in length.
