Material Delay for DS Natty?

I was wondering if there was any material delay for DS Natty or any W&C leather for production? I purchased a pair of LTTs and a Pullman at the same time yet the Pullmans are already finished and shipped. There’s no word of the LTTs; which is surprising since I thought the pull-on boots typically take longer for production than a lace up. I also have a Dr. Sole outsole on the LTTs too so maybe the combo of the leather & outsole is making it take longer. Wondering if anyone else knows or has a similar experience.
