INTERCHANGEABLE THONGS – PRINTABLE SIZING CHART

Although the thongs may vary a few millimetres it is best to measure your foot or a pair of old thongs 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.

The Boomerangz size range is based on the MENS US size range. Although they are unisex – 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 with the sizing charts below   🙂
