Occasionally when the thongs are brand new, they can squeak if some sweat develops underneath the foot. The problem should go hopefully away once the thongs are worn in and some of the initial sheen wears off. The thongs almost always squeak when wet such as after swimming whether they are brand new or well and truly worn in.
However, once the thongs are worn in, under normal circumstances they should not squeak during normal walking (unless they get wet).
In the instance the thongs are squeaking with normal walking (they are not wet), there is two most common causes:
- Sweat may be developing between the thong and the foot causing the squeaking noise.
- The thongs have come into contact with something that is causing them to squeak (normally dirt, microscopic dust or a chemical agent such as shampoo or conditioner).
If your thongs are squeaking and it’s not because they are wet, then we suggest:
Washing them in warm water and give them a vigorous scrub with a scrubbing brush or green scourer then thoroughly drying them with a towel.
We often find that when this happens the thongs have some how come in contact with something (we don't know exactly what) and washing and drying them often fixes this!
If the thongs continues to squeak during normal walking, after they have been well worn in and after you have vigorously washed them, normally ‘roughing up' the surface of the thong with some coarse sandpaper fixes this.
