All Chucks fit the same. I usually have to opt for a larger size because they are a bit narrow for me but I have wide feet. I also have very high arches and they don't really provide a lot of support but an insert will help a lot. However, I heard that they are adding a little bit more arch support to the design in the future. That said I've had a pair of these for almost 15 years. I wore a small hole on the side where my foot is a bit too wide for the shoe, worn down the sole on the heel and near the ball of my foot but the sole is still intact. I doodled on them and they are still one of my favorite pair of shoes. I wouldn't recommend them for sports but as a fashion sneaker they are ideal. They come in so many colors and you can pretty much get away with wearing a nice pair with anything. The price makes it affordable to own several pairs in various colors.
