I am a size 9 foot and I requested (and received) a size 9. I can sometimes fit an 8.5 if the manufacturer has odd sizing, but usually a 9 will fit. Feet can be a little wider than average, but I don't need a large size to be comfortable (none of my shoes are W). They have an aesthetic shape that is somewhat narrow in width. The material is flexible and I think it can stretch over time. Hope. There is no problem with the length. The insole is soft with a cork image. Pretty comfortable and I suspect they are meant to be less absorbent/help avoid odor when worn barefoot. The outsole has no noticeable traction but is grippy enough on my hardwood floors. However, be careful on wet/slippery surfaces. I don't really have any complaints other than that the comfort isn't as good as it could be. So solid 4 stars.
