I'm delighted so far. I have only worn them a few days, so we will see how they hold up. I have looked for a long time for something to replace a Puma pull-on walking shoe. As too often happens, they discontinued this marvelous shoe and replaced it with something totally inferior compared with it. I am very active, and I wanted something I could wear to the gym with my tights, but also with casual pants to go out socially are to athletic events (as I did with the Puma product.) I wear a 10 normally--sometime a medium, often a narrow if it is available. I have quite a high arch and what most would probably consider a narrow heel. I ordered a 9.5 medium, based on other reviews. I wear Vionic a lot, in everything from slippers to sandals, and they usually work for me. Sometime the sandals are a bit short. These were perfect for me out of the box. They do seem like they may stretch, as they are largely fabric. Have my fingers crossed, because so far, so great.
