Abstract: A shoelace fastener device for shoes includes an upper having two sides and a tongue to be tightened using at least one shoelace. This device includes a guide device of the shoelace, extended and positioned, in use, substantially longitudinally in relation to the tongue. The guide device enables one or more portions of the shoelace to be contained and guided along the tongue so that these portions are arranged substantially aligned with the longitudinal direction of the tongue. The guide device includes at least one flexible strip appropriately shaped so as to form at least one cavity capable of accommodating and guiding one or more portions of the shoelace.
