These shoes are very comfortable. I normally wear either a size 6 or a 6 1/2 in shoes. The 6M fits perfect in these, with enough room for thick socks! I have slightly wide feet, but the medium width in these fits great and has plenty of room for my toes. Unless you have very wide feet, you may want to purchase the medium width instead of the wide width. I'm fairly certain that if I had purchased the wide width I would have need a smaller size in order for them to not be too big. These shoes are way more comfortable than my Danskos; they have an excellent insole with great arch support. I purchased the dark brown oil color, which looks good with jeans for casual wear. I plan on purchasing either the black for white for work. They have a slip resistant sole.
