Half cut frames are the 'in-thing' at the moment and these new styles ooze style and show flashes of the beaches of South California where they were inspired from. One of the most unique styles in our range, they have quickly become our most popular. 

This range looks good on everyone and at the same time provide crucial UV400 and polarised protection for your eyes. 
Polarised lenses reduce glare from surfaces like water, the road, and car windows. 

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.


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   🙂
