I am especially interested to hear what DWFII and other residents shoe maker think about this. When you are buying a cowboy boots you are advised that there should be some heel slippage until the sole breaks in. But what about other footwear? Shoes, Chelsea boots? Those with rubber soles etc? The reason why I am asking is because I bought a Belgrade boot from RL http://www.ralphlauren.com/product/i...ductId=3711092 These boots seems to to have some sort of linen lining in heels, like a loafer shoes. This lining firmly locks my heels in place, there is no movement or slippage of any kind. My question is should heels flex a bit when you walk? What are your opinions or experiences? PS. Do not mind that spelling mistake in title
