WARNING: These shoes run 1/2 size small. I have been wearing vans for 35 years and for the past 25 years I have always worn a mens size 9. When I ordered a 9 and put them on they were too small (my toes touched the end of the shoe). I reordered a size 9.5 to correct this and a 10.0 would have also worked (just a little big but not much I figure!) order at least a +.5 size to avoid the issue I had. Besides this these are awesome shoes. I use 5-10s and these and like the Vans more because they are almost as sticky but my foot stays cooler on hot days.
