Fits true to size for me and as expected for similar, knit flats of this type. Super comfortable. Not a lot of arch support (although there is some), and definitely has a lighter, "barefoot" feel to the sole and overall construction. These are ridiculously flexible and lightweight. You could tuck them into a backpack easily if you were traveling carry-on only and they'd be just fine. But most importantly, they are comfortable. The cut is comfortable, even for sensitive, swollen feet; the soles are grippy enough to not be slippery on the floor or ground. The insole is cute with decoration. I don't know how they'll hold up long-term, but they are a truly great value for the current list price, due mainly to the comfort level. I tried them on the first day, taking off house slippers, and I wore them for the rest of the day. They were that comfortable. I am able to wear them with toe spacers inside without finding that my toes are strangled, or that I develop blisters. They are wide enough to be comfortable, but do not appear to be "boat" like, as some "wider" shoes may be. The particular design I got has a definite retro feel to it, and probably is best with longer skirts or pants, but it is cute and versatile. The fabric does not appear "shiny cheap". When I wash them, and I definitely will -- I prefer washable shoes -- I will dry them with shoe forms inside them to keep their shape. They are a really lovely pair of shoes and would work for probably almost anyone's wardrobe.I own a number of knit shoes, from sneakers to boots to clogs, sandals, driving Mocs, flats, boat shoes and loafers. I am a real fan of them due to my particular foot issues. The sizing of that brand is, well, eccentric to be kind. The price is significantly higher. However, the cut of these shoes is what makes them stand out to me, around the top of your foot and around the arch. There is more coverage than from typical knit flat shoes (you know the brand, it's a major one, with lots of ads and a blue streak on the back); I own a pair of their loafers as well, and these are similar, although there is a significantly thinner sole to these shoes and they are lighter weight and more flexible. These might be a tad more breathable. But for the cost differential, if you do not already own knit shoes, these are a definite must try first.
