I definitively hate the act to drop out as garbage something for a bit of damage, sometimes is inavoidable and I suffer about this.
So, About my beloved havaianas shoes I've made something of useful; the havaianas respawn.
It's a simple two parts thing that work with a zip tie of 2,3 mm.
The pics show what is it and how it work.
There are two version, choiche that you think more right.
Enjoy forever everywhere with your havaianas .
