I've done this before. I had a pair of running shoes that were so perfect that I bought 3 pairs and when time to replace, boom, no issues with finding them or having to locate something new. It was awesome. I liken that to the way some women only have one brand\model of bra for their daily wearer and buy 5 or 6 of them at a time. I had a girlfriend once that I thought was going to have a nervous breakdown after they changed or discontinued a specific model of bra she had been wearing for 10 years or something like that. At that age, I had no idea how that garments are so desired and really have a hard time trying something else to some people.
