Hello! We can definitely help supply this. We don't need anymore photos, but we will need to know how thick your shoe is before we can recommend a match. Once I know that, I'm very confident I can get you one that matches.

You may find it easier to measure the thickness if you remove it first.

What's the best way to remove it from the track it's in? Thanks in advance

There are a couple different methods, depending on the window. I recommend watching the videos below, which expand on these methods pretty thoroughly.
