Help Finding New Foam Weatherstriping

I have double glide tilt n wash windows with warn out weather striping. I do not know the manufacture of the windows or model numbers. My current weather striping seems to be soft to the touch. It has a flat bottom foam filled. I am attaching the pictures of the striping showing flat bottom which allows it to secure on the window frame. I also sent pictures of the window showing the placement of the striping and measurements which are 1/4 by 1/4.
I did by 1/4in bubble striping which is not pliable enough when snapping window into place causing it to pop out of place.
