Nordstrom in downtown SF (SF Center) has a good selection and a terrific return policy. They mostly have Aldens, AE and Ferragamos though; maybe a few Santonis. Neiman Marcus has some Lobbs and the usual Italian designer shoes (Gucci, Prada, Testoni, Tod's etc). Saks has Heschung, Testoni, Zegna, and the usual Italians. Malouf's in Burlingame has a selection of Ed Greens.
