Sharkskin & Stingray are tough leathers & need to move to keep from drying out & cracking especially in climates with very low humidity or moisture. Boot trees are not recommended. You can actually split lizard skin by using boot trees. The soles of well designed cowboy boots are made to turn up on the toe.[/QUOTE] It is a conundrum in that I live in a humid climate where it seldom drops below 50% but it is wet....so it is good weather for my lizard and python boots in the closet I can't wear them on most days as it is raining and very wet. Did not know that boots were supposed to curl up at the toe. Personally, as a northern city boy hate the look and use my trees religiously. I have two pair of Lucchese branded boot trees with the high arch and will now be cautious about using them in my lizards . Not knowing they were supposed to curl my first though was "damn, it is too bad Snuff and Montie did not take better care of such great boots." Mea culpa, mea culpa!
