The great thing about style is that it can be applied in a practical way. What you learn from a plethora of style guides can be directly transferred and translated into your own interpretation of style. There is no room for erudition in matters of style. It goes without saying then that part of the learning process is in knowing the exact names of things, what they are and their function. Which brings us to the anatomy of a shoe.
Nothing goes a long way in illustrating a point than illustrations. I have always been somewhat confused by the open and closed lacing in shoes, until I came across an article on Style Forum addressing: the leather used in the various methods of shoe construction, welted shoes, Blake construction, reverse welts, etc. The article is concise and comprehensive. I learnt a lot from it, and you can too.
