I agree with that assessment. On far too many occasions, I've purchased shoes (typically at discount) that I thought would stretch out over time. In almost every case, the shoes were unwearable. I came to the conclusion that shoes MUST fit perfectly out of the box or I won't buy them. Like you, I get pressure on the little toe on one foot. I've been able to make slightly large shoes work with insoles or even thicker socks but never had luck with shoes that were snug in the store. It's cost me more than I'd like to admit over the years.
patrick I've often been in the same situation as a person who has a wide foot. Even on SF people seems to believe that stretching does happen with wear and a little snugness is desired. I sometimes wonder if it's the shoe that stretches after a couple of wears or just the leather getting softer from wear.
