While the straps of Archies Flip Flops are tighter than normal flip flops, unfortunately, over time, the strap will eventually stretch and lose some of its original tightness, the same way clothing will stretch over time if you wear it a lot. Once stretched, the strap will not return to its original tightness.
However, if your strap has stretched, there are a couple of tricks that you can try that can re-tighten the strap:
Both methods to re-tighten the strap require very hot heat sources, so please be EXTREMELY CAREFUL not to burn yourself and take all precautions necessary!
Option 1 - Hot water method:
Boil the kettle. Put the plug in the kitchen sink. Tip the boiling water into the sink. Place the flip flops upside down so that the strap is in hot water. Leave flip flops in the water for 5 mins and then take out. Pat the flip flops to dry and wait until fully cooled before trying them back on. We recommend a full 8 hrs.
Option 2 – Hairdryer method:
You normally need a fairly decent/powerful hairdryer to be able to do this.
Using a hairdryer, on the hottest setting, apply the hot air to the strap for approx 2-3 minutes.
*Please keep your hands away from the hot air source and be careful not to overheat your hairdryer.
This should shrink the strap down and make it tighter again. Allow the flip flops to fully cool before trying them on again. We recommend a full 8 hrs.
*Be CAREFUL NOT TO OVERHEAT your hairdryer.
Both of these methods should tighten the strap.
Of course, with both methods. Please take EXTREME CAUTION not to burn yourself!
In summary, any concentrated heat source applied to the strap area only will shrink the strap down and re-tighten it. Just allow the flip flops to fully cool before trying them on again.
