Size Guide


The bases will vary a few millimetres. It is best to measure your foot or an old pair, from the centre of the heel, to the top of your big toe.
Please always check your size before ordering as you will incur postage fees should you need to swap for a different size.


Do you have really narrow or really wide feet?
You can customise your fit to perfection! Smaller or larger sized straps can be added to different sized bases. Slim straps can be added to the corresponding Mens / Unisex base and vice versa.

The Boomerangz size range is based on the MENS/UNISEX US size range. Although they are UNISEX (it says UNISEX on the base) – This means that if you are ordering a ladies slim style and you are normally a 9, you will need to order a 7/8 instead. If you are normally a 7/8, you will need to order a 6 and so on… best to measure your foot or an old pair and use the sizing charts provided.
