I got a half size bigger because the memory foam lines run small. And I liked the fit and comfort so much I bought a second pair in gray. One pair for work, one pair for workouts. Plus, Sketchers last the longest by far of any of brand I've owned.
Update: I have changed my 5 star rating to a 1 star rating because not even 4 months in the memory foam insole has ripped! I am extremely mad and upset about this failure of product (i.e PO'd). The pair (same model) I purchased before this one lasted over a year before it's insole ripped, and the tread started to come apart, which is why I purchased this pair. It now feels as though I have something in my shoe right under my heel, very annoying. These are my work shoes, so they do not get a lot of "ware and tear" due to the fact I mostly stand in one spot in my lab. There is not running, and very little walking. I will be contacting the seller about this.
