Boomerangz – Interchangeable thong range – Sizes & Colours Video

Our patented range of thongs / flip flops is interchangeable which means you can mix and match your bases and straps in less than 30 seconds – no tools, no fuss! Different coloured bases and different coloured straps allows for multiple colour combinations.

INTERCHANGEABLE THONGS – PRINTABLE SIZING CHART

The thongs will 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 (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 old thongs with the sizing charts below ¬† ūüôā

Slim straps can be added to the corresponding Mens / Unisex base and vice versa.
