For each pair of women’s Numentum shoes sold through OnlineShoes.com this month, Ahnu, a division of Deckers Outdoor, will donate $5 to the Breast Cancer Fund, the leading organization working to identify and eliminate the environmental causes of breast cancer. It’s all a part of Ahnu’s “Prevention Mission” to raise $100,000 for the Breast Cancer Fund this spring. In April, the initiative will expand to more than 150 retailers nationwide.
