Use shoe goo and clamp it down over night , I promise you it will never come loose. I have tons of shoe goo tricks that will blow your mind. I figured out a way to use it as to where if you put it in the places I tell you to in the way I tell you to you will never ever have cracks at stress points I promise you . It’s like a miracle glue . Been using it for years if it can hold a shoe together and designed to be walked on it can damn sure hold elastic to its mounting point. I mean think about it it’s made to be used on the bottom of your shoes but yet Flex and hold at the same time . I actually used it on a return pipe on my radiator that goes into my Volvo it hasn’t come loose yet yes I fixed a radiator pipe on my Volvo with shoe goo. More on that later.
