The weather stripping on the outside edge of our casement windows is very deteriorated. It is foam filled and roughly circular. It extends out of the track about 1/4" inch diameter. I can't see the portion in the track, but it does not look like it is offset, just tucked into the track. It is white in color. In the attached photo there are actually three spots on window with this weather stripping. Only the outside one (which is exposed to the weather) is deteriorating. Would probably need at least 16 feet to replace the outside edges on both windows. What do you recommend? FYI,, I have ordered window springs from you before for out double hung windows.

I'm sorry to say that we can't make a recommendation based on the information provided. The only way to properly identify weatherstripping is to remove a sample of the original and use the shape and size of the end profile as a reference. The video below will clarify what I mean.
I understand that your original is deteriorated, so this is all easier said than done, but there's no other way to find a match. It has to be done, so try your best to remove an intact sample and get precise dimensions.
