It took me about two days to realize how much I liked these shoes. I did wear them with light socks for the first two days but then found it unnecessary. I have wide feet and they fit perfectly, which probably means they are not good for someone with narrow ones. I usually wear a 7 or 7 1/2 C/D in New Balance and the 7 1/2 B was just the right size, which probably means most people should go up one half size. I love the freedom of wearing the minimus without socks. They have no arch whatsoever and might take some getting used to. I do not jog in them but wear them morning until night and use them for walking the dog. However, for long walks or sightseeing, I prefer my NB846 walking sneakers which have much more support and cushioning.
