I agree fully. Having comfortable shoes with reasonable lifespans isn't a luxury. If you spend more money and get a proportional increase in quality, that's not luxury. A luxury good occurs when the marginal increase in quality cannot be justified by the increase in price. For example, you could buy a quartz Casio for $25 that's more accurate than a $10,000 mechanical Rolex. Both tell you the same time.
