This model has a regular fit. We suggest you take your usual size.This model can be washed in the washing machine, removing the insole first if it is removable.For cleaning, use a cold and short program or one for delicate items.Keep in mind that, if it is a pattern in dyed canvas, it may lose color in contact with water.Let them dry in the shade to prevent the color fading in the sun. You can insert newspaper paper inside to absorb moisture and maintain shape.Do not rub the localized spots, as this could cause the dirt to penetrate deeper and cause a loss of color in that area.
