Betty; I think you will just have to try Sanitas in a brick'n'mortar store. Even within Dansko Pro models, I find some fit me better than others, and I just bought thin insoles so that a pair doesn't fit me quite so loosely. I suspect that Sanitas will not work as well for you, but then some pairs might. As I recall, you bought some NYDJ jeans a few months back that you really, really like. Probably, a lot of NYDJ jeans will work for you, but then some might not. That's been my experience, and that's what the reviews reflect. Sometimes it has to do with what factory they use or with quality control in general. Same with shoes.
Oh, yeah. And just when you think you've found your holy grail, the fit model or last changes. Such is life.
If/when you try Sanitas, please report back. I'd like to know whether they're worthwhile to pursue for my wide but low volume feet.
