I haven’t had a chance to use it on my new Backcountry boots yet, I normally use conditioner sparingly and the Walnut Timberjack leather on these boots is still very supple and oily/waxy after a month’s wear, often in very wet conditions. I have used this same product on other leather hiking boots since many years, it works very well. Just be aware that it darkens leathers appreciably, use Pecards instead if you want the colour to remain unchanged.
