I say get them!
Lol. Those boots will never go down in price so if you want them, now is the time for that "cheaper" price. Gosh I don't own a pair of LV boots; however, I was told they run small and run the same way the Chanel Combat Classic boots run. I am a true 9 in US shoes. I bought the Chanel Classic Combat Boots (the ones with the CC 19 looking hardware on the leather flap that goes around the ankle).
Size 40 (10) was perfect. No need for super duper thick socks or shoe insert to make them fit right. I tried on the 39.5 first and my big toe was right on the tip, making it uncomfortable and that was using the super thin black socks Nordstrom gives you for trying on shoes. I have slim narrow feet for reference. Hope this helps. You can always buy the size you think will work to "lock in the price" and if it is too small or too large just exchange for the right size. I do believe the exchange will be an even exchange if you exchange for same exact boot just different size if the price increase happens after your purchase. I would confirm tho with customer service. Just do exchanges or returns within 30 days of purchase.
