This is a great fix for comfortable sandals or flip flops which you just want to stay on and wear all summer long.
I had been looking for adult sized stay on straps for flip flops for a while and couldn't find any anywhere to buy these. The tutorials i did find were complicated involving sewing machines and elastic which makes for a big project for me so i stumbled n this idea and feel i must share this with everyone.
1. bra strap from a strapless bra- that's it.
Note: You want to choose the straps with the best hook part so that it stays on and doesn't slide around when you are wearing them.
The black bra strap in my photo is the most secure and has been worn all day long without slipping out.
Notice the knob at the hook part and it's made of metal which is better than plastic bra strap hooks
