Yes, absolutely. I bought the Ariat Women's ATS Footbed - SquareToe for my Dan Post snip toe boots. I trimmed the end just a tad and the footbed is perfect.
I take the footbed out of my Ariat lacer boots and put them in my boot shoes when I wear them. Just buy the appropriate style toe - round for round and square for square or snip toe boots in the correct size. You can always trim the footbed with scissors a bit if needed.
