Can these be boiled? Mine is losing its shape and so the ends are pinching me bad.

I boiled mine to sanitize them when I first got them. Seemed fine.

If i measured 15mm would these be correct or should i purchase a 17mm insert?

I believe it depends on which pump you are trying to get. Willow needs exact sizing, I’ve heard to go up in spectra. I bought 15 and 17 and use whichever one was more comfortable, which was the true to size, 15s. Hope that helped!

If anyone used these with momcozy s9 how well did they work??

They work very well. I used them in the 24mm momcozy
