Query: This ia a must have

If you have quality boots, you need to have quality boot trees. I have a pair of Tony Lamas and a pair of Justins, that I meticulously care for. These trees help my boots maintain their shape, and the cedar just plain looks and smells good. Regarding size, go large/extra large unless you're a lady. I wear size 10-1/2 boots, but I bought the largest size boot tree they offer, and it fits perfectly due to the spring tension. These trees are solid and reliable. As stated,if you have good boots and want to keep them for the long haul, you need these trees.
