Canvas shoes are perfect for summer, first because of their relaxed appearance, and second because they can help keep your feet cool during hot days. If the canvas is very thick and tightly woven, you may find that they are no cooler than any other shoe. So you may want to look for a canvas that is woven so that there is actually open space between the strands. This means sweat can escape, moisture can evaporate, and air can enter the shoe.
Love these – very casual but clean:
