I have thin flat feet so anytime I read a review that says a shoe is narrow, I go for it. My favorites are the Asics Sonoma, and these are my 2nd favorite. They provide good support for flat feet. However, there is a mystery about them I've yet to solve. My first pair was the white/silver/aqua  flowered pair that fits perfectly. I then bought the shark/aruba blue pair that's almost perfect - sometimes a small rub against big toe on left foot - my left foot is a tad longer. Then i bought purple/silver/mint - again almost ok if I don't wear thick socks. The purple/orange shoe fits the worst, kills my left big toe. I've measured the shoes, all are the same. I've felt around inside the toe boxes with my hands and all are the same. I don't see how one pair can be perfect, one pair yucky, and the rest in-between! I also have the black pair (ok I'm a sneaker freak) which so far seem ok.  One day after having my toe abused by the purple/orange pair, I put on the flowered pair to see what would happen  and again they were perfect. I've decided that all but the flowered and black pairs  are relegated to spring/summer when I can wear thinner socks.
