A ventilative PU midsole or sole pad includes at least a solid layer, which is composed of plural PU strings, and the strings are overlaid mutually and irregularly to become multi-layers with numerous gaps among one another, so that the solid layer is provided with good ventilation to be used as a midsole for a shoe, or directly used as a sole pad. Thus the midsole has a good ventilation, preventing a wearer from getting skin disease or bad foot odor, and at the same time it may have no odor, no smell and environmentally friendly, letting a wearer feel comfortable without getting tired in wearing.
