After having been a Blundstone 500 (http://www.blundstone.com/product_info.cgi?subpageID=classicslifestyle&sub_categoryID=130278#) devotee for a few years, I've officially traded up for a pair of RM William's Gardeners (http://www.bobmicklers.com/istar.asp?a=6&id=B530G06!RLC), which are re-soleable and tough as heck.
Easy on, easy off, and can look as good with dress pants as jeans. A+++ would totally buy again except I DON'T HAVE TO because they will last a million years.
